Abstract:

Electrospun nanofibrous mats are ideal substrates for metalorganic frameworks (MOFs) crystal deposition because of their specific structural parameters and chemical tenability. In this work, we utilized organic-inorganic hybrid electrospun fibrous mats as support material to study the deposition of various MOF particles. HKUST-1 and MIL-53(Al) were produced through solvothermal method, while ZIF-8 and MIL-88B(Fe) were prepared using microwave-induced heating method. The synthesis procedure for both methods were simple and effective because the hybrid nanofibrous mats showed considerable affinity to MOF particles and could be used without additional modifications. The obtained MOF composites exhibited effective incorporation between MOF particles and the porous substrates. MIL-53(Al) composite was applied as fibrous sorbent and showed enhanced adsorption capacity and removal rate, as well as easier operation, compared with thepowdered sample. Moreover, MIL-53(Al) composite was easier to be regenerated compared with powder form.

Abstract:

The efficiency of Lake Victoria in providing its ecosystem services to riparian states, both immediate and along the Nile river basin, is strongly related to its water quality. Over the past few decades, eutrophication has increased in the lake arising from increased inflow of nutrients. This study was carried out in the Murchison Bay area of Lake Victoria with the aims of assessing the progress of eutrophication nutrient enrichment into the lake between 1990 and 2014. Using Landsat satellite floating algae index (FAI) products and data from laboratory analysis of water samples, the study revealed that floating algae reoccurred periodically with coverage varying between 1 and 18 km(2). The findings also indicated that the range of nitrate-nitrogen concentrations increased greatly with maximum concentrations recorded at 31.2 mg l(-1) in 2007 from 0.084 mg l(-1) in 1990. The soluble reactive phosphorus concentration range showed a maximum of 1.45 mg l(-1) in 2007 from 0.043 mg l(-1) in 1990. The chlorophyll levels increased from an average of 17 mu g l(-1) in 1992 by threefold in 1996 but had however declined and halved in intensity by 2011. The eutrophication that has occurred in Lake Victoria over the past decades has been due to pollution from industrial, residential, and agricultural areas within the catchment.

Abstract

Water and energy are closely connected and both are very important for human development. Waste-water treatment plants (WWTPs) are central to water-energy interactions as they consume energy to remove pollutants and thus reduce the human gray water footprint on the natural water environment. In this work, we quantified energy consumption in 9 different WWTPs in south China, with different treatment processes, objects, and capacities. The energy intensity in most of these WWTPs is in the range of 0.4-0.5 kWh/m(3) in 2014. Footprint methodologies were used in this paper to provide insight into the environmental changes that result from VVWTPs. A new indicator "gray water footprint reduction" is proposed based on the notion of gray water footprint to better assess the role of WWTPs in reducing human impacts on water resources. We find that higher capacity and appropriate technology of the WWTPs will result in higher gray water footprint reduction. On average, 6.78 m(3) gray water footprint is reduced when 1 m(3) domestic sewage is treated in WWTPs in China. 13.38 L freshwater are required to produce the 0.4 kWh electrical input needed for treating 1 m(3) domestic wastewater, and 0.23 kg CO2 is emitted during this process. The wastewater characteristics, treatment technologies as well as management systems have a major impact on the efficiency of energy utilization in reducing gray water footprint via these WWTPs. The additional climate impact associated with wastewater treatment should be considered in China due to the enormous annual wastewater discharge. Policy suggestions are provided based on results in this work and the features of China's energy and water distribution. (C) 2015 Elsevier Ltd. All rights reserved.

Abstract

The application of nanoparticles has raised concern over the safety of these materials to human health and the ecosystem. After release into an aquatic environment, nanoparticles are likely to experience heteroaggregation with biocolloids, geocolloids, natural organic matter (NOM) and other types of nanoparticles. Heteroaggregation is of vital importance for determining the fate and transport of nanoparticles in aqueous phase and sediments. In this article, we review the typical cases of heteroaggregation between nanoparticles and biocolloids and/or geocolloids, mechanisms, modeling, and important indicators used to determine heteroaggregation in aqueous phase. The major mechanisms of heteroaggregation include electric force, bridging, hydrogen bonding, and chemical bonding. The modeling of heteroaggregation typically considers DLVO, X-DLVO, and fractal dimension. The major indicators for studying heteroaggregation of nanoparticles include surface charge measurements, size measurements, observation of morphology of particles and aggregates, and heteroaggregation rate determination. In the end, we summarize the research challenges and perspective for the heteroaggregation of nanoparticles, such as the determination of dieter values and heteroaggregation rates; more accurate analytical methods instead of DLS for heteroaggregation measurements; sensitive analytical techniques to measure low concentrations of nanoparticles in heteroaggregation systems; appropriate characterization of NOM at the molecular level to understand the structures and fractionation of NOM; effects of different types, concentrations, and fractions of NOM on the heteroaggregation of nanoparticles; the quantitative adsorption and desorption of NOM onto the surface of nanoparticles and heteroaggregates; and a better understanding of the fundamental mechanisms and modeling of heteroaggregation in natural water which is a complex system containing NOM, nanoparticles, biocolloids and geocolloids.

Abstract

Efficient treatment of solutions and solid wastes containing Rhodamine B (RB), a common dye with potential carcinogenicity and sometimes used illegally in food industry, is of great importance because inappropriate treatment may lead to serious human and environmental risks. A novel nanomaterial, the mesoporous silica nanosheets prepared via electrospinning and calcination are applied to the adsorption of RB from aqueous solutions in this work. This sheet-like material is superior to classic powder adsorbents in recoverability, while good availability and stability favor its practical application. The effects of key parameters such as system pH, stirring rate, initial concentration, and contact time are studied. The adsorption isotherm type and the kinetic characteristic are analyzed. The results show that the mesoporous SiO2 nanosheets are efficient in removing RB from aqueous phase, presenting great potential to become a practical dye adsorbent. Regeneration experiments show that this novel adsorbent can be activated by ethanol extraction process. This study provides the academic field with a successful application case of nanostructured materials, which can be applied to a wider range of dyes similar to RB in physicochemical properties, showing prosperous value in advanced environmental purification.

Abstract

A strategy for in situ fabrication of nanoscale-thin layers of anatase TiO2 coated on the metal-organic framework (MOF) material, MIL-53(AI), is developed. The preparation conditions for crystallized TiO2 are normally incompatible with the thermal and chemical stability of MOFs. Based on our strategy, we found that the redundant organic ligands (1,4-benzenedicarboxylic acid, H2BDC) within the pores of the as-synthesized MOF play a key function in the protection and support of the framework during hydrother- mal loading of the TiO, precursor, as well as in preventing the infiltration of the precursor into the pores. After annealing, a nanoscale-thin layer of highly crystalline anatase Ti02, with a thickness of 6-10 nm, was successfully attached to the external surface of the MIL-53(AI) crystals, while the porous framework remains intact. The core-shell structure of the MOF@TiO2 nanocomposite endows the resulting materials with additional optical response and enhanced moisture and chemical stability.

Abstract

Fly ash originating from municipal solid waste incineration (MSWI) is potentially hazardous waste and is harmful to the surrounding area once it enters the environment. In this study, we measured the physiochemical properties of fly ash derived from domestic waste incineration as well as the leaching toxicity of heavy metals in fly ash was contained. The results suggested that the porosity of fly ash is relatively high, and the leaching concentration of heavy metals can be greatly reduced through densification strategies in which fly ash is stabilized by chemical agents. The adsorption-desorption curve of fly ash had an obvious hysteresis loop that belongs to the H2-type hysteresis loop. Fly ash was typically mesoporous, and the silicate in fly ash was relatively stable. Its glass phase contents were higher-this allowed it to be used in ceramic tile decoration. In addition, Pb and Cd were the major heavy metals in fly ash. These heavy metals were mainly distributed in the residue. Heavy metals were easily leached out under strong acid or alkaline conditions. (C) 2015 The Institution of Chemical Engineers. Published by Elsevier B.V. All rights reserved.

Abstract

The increasing and wide use of nanoparticles (NPs), including TiO2 and Ag NPs, have raised concerns due to their potential toxicity and environmental impacts. Kaolin is a very common mineral in aquatic systems, and there is a very high probability that nanoparticles (NPs) will interact with these clay minerals. We studied the effect of kaolin particles on the aggregation of NPs under different conditions, including the role of pH, ionic strength (IS), and humic acid (HA). We show that kaolin reduces the energy barrier and the Critical Coagulation Concentration (CCC) at pH 4. At pH 8, even though the energy barrier of the system without kaolin increases, kaolin promotes NP aggregation via heteroaggregation. When IS is equal to or greater than the CCC, on the one hand HA promotes aggregation of TiO2 NPs, but on the other hand HA decreases the rate of Ag NP aggregation because the existence of a surface coating may limit the adsorption of HA on these Ag NPs. In addition, the presence of HA increases the energy barrier and the CCC of the binary system (kaolin + NPs). Thus, the complex interactions of clay, NPs, IS, pH, and HA concentration determine the colloidal stability of the NPs. We find that kaolin is a potential coagulant for removal of NPs that behave like Ag and TiO2. (C) 2015 Elsevier Ltd. All rights reserved.

Abstract

The synergistic effect of the combination of polyaspartic acid (PASP), polyepoxysuccinic acid (PESA), polyamino polyether methylenephosphonate (PAPEMP), sodium gluconate (Glu) and Zn2+ on carbon steel corrosion was investigated using weight loss and electrochemical measurements. The combination of PASP, PESA, PAPEMP, Glu and Zn2+ is an environment-friendly inhibitor and exhibited mixed-type inhibition behaviour. The composite efficiently inhibited corrosion on carbon steel at relatively low dosages in severely corrosive soft water media. Atomic force microscopy (AFM) images and X-ray photoelectron spectroscopic (XPS) spectra further confirmed the formation of a protective film composed of the adsorbed inhibitor molecules on the carbon steel surface against corrosion attack.

Abstract

Three aluminum compounds, namely alumina, aluminum hydroxide, and boehmite, are probed as the metal sources for the hydrothermal synthesis of a typical metal-organic framework MIL-53(Al). The process exhibits enhanced synthetic efficiency without the generation of strongly acidic byproducts. The time-course monitoring of conversion from different aluminum sources into MIL-53(Al) is achieved by multiple characterization that reveals a similar but differentiated crystallinity, porosity, and morphology relative to typical MIL-53(Al) prepared from water-soluble aluminum salts. Moreover, the prepared MIL-53(Al) constructed with the three insoluble aluminum sources exhibit an improved thermal stability of up to nearly 600 degrees C and enhanced yields. Alumina and boehmite are more preferable than aluminum hydroxide in terms of product porosity, yield, and reaction time. The adsorption performances of a typical environmental endocrine disruptor, dimethyl phthalate, on the prepared MIL-53(Al) samples are also investigated. The improved structural stability of MIL-53(Al) prepared from these alternative aluminum sources enables double-enhanced adsorption performance (up to 206 mg g(-1)) relative to the conventionally obtained MIL-53(Al).

Abstract

China is the largest producer of iron and steel in the world. This heavy industry is characterized by significant water consumption and numerous water-related hazards. In this study, we propose the use of water footprint instead of conventional indicators (fresh water consumption (FWC) per tonne of steel or water consumption (WC) per tonne of steel) for the iron and steel industry. Using an iron factory in Eastern China as an example, we develop a water footprint calculation model that includes direct and virtual water footprints. A system boundary analysis method is then proposed to develop a common and feasible industrial water footprint assessment methodology. Specifically, we analyze the characteristics of the iron and steel industry from a life cycle assessment perspective. A water risk assessment was performed based on the results of the water footprint calculations. The selected iron factory has a water consumption (blue water) footprint of 2.24 x 10(7) m(3), including virtual water, and a theoretical water pollution (gray water) footprint of 6.5 x 10(8) m(3) in 2011, indicating that the enterprise poses a serious risk to the water environment. The blue water and gray water footprints are calculated separately to provide more detailed water risk information, instead of adding these two indicators, which has less environmental significance.

Abstract

Mesoporous alumina nanofibers were obtained by a combined method including three steps, as the sol-gel process, electrospinning and calcination. Dendrimer polyamidoamine was employed as the structure directing agent to form the mesoporous structures. The electrospinning process was applied to providing the alumina with a fibrous morphology and a flexible property, which were fixed during calcination. Products with different crystal structures and physicochemical properties were obtained at different calcination temperatures. The typical mesoporous alumina nanofibers showed a surface area of 417.7 m(2)/g according to the Brunauer-Emmett-Teller method and a total pore volume of 0.40 cm(3)/g on the basis of the Barrett-Joyner-Halenda model when the calcination temperature was set as 450 degrees C. The possible formation mechanism of the mesoporous structures was analyzed. The typical product was applied to the adsorption of Methyl Orange from aqueous solutions. The influence of system pH on adsorption, the adsorption isotherm feature, the kinetics and the reuse performance were investigated. (C) 2014 Elsevier B.V. All rights reserved.

Abstract

Paracetamol is a widely used as an analgesic and an antipyretic that can easily accumulate in aquatic environments. This study aimed to enhance paracetamol removal efficiency from water by combining the biocatalytic activity of horseradish peroxidase (HRP) with the adsorption of nanofibrous membrane. Poly(vinyl alcohol)/poly(acrylic acid)/SiO2 electrospinning nanofibrous membrane was prepared with fiber diameters of 200 to 300 nm. The membrane was made insoluble by the thermal cross-linking process. HRP, which was previously activated by 1,1'-carbonyldiimidazole, was covalently immobilized on the surface of nanofibers. Immobilized HRP retained 79.4 % of the activity of free HRP. The physical, chemical, and biochemical properties of the immobilized HRP and its application in paracetamol removal were comprehensively investigated. Immobilized HRP showed better storage capability and higher tolerance to the changes in pH and temperature than free HRP. Paracetamol removal rate by immobilized HRP (83.5 %) was similar to that of free HRP (84.4 %), but immobilized HRP showed excellent reusability. The results signify that enzyme immobilized on nanofibers has great application potential in water treatment.

Abstract

We studied the corrosion inhibition properties of a combination of polyaspartic acid, polyepoxysuccinic acid, polyamino polyether methylenephosphonate, and sodium gluconate for carbon steel in recirculating cooling water. Characterization employed weight loss measurements, Tafel polarization, electrochemical impedance spectroscopy, X-ray fluorescence (EDX), and atomic force microscopy (AFM). The results show that the composite efficiently inhibited corrosion on carbon steel at relatively low dosages in severely corrosive soft water media. The EDX spectrum determined the nature of the adsorption layer on the steel surfaces. Scanning electron microscopy and AFM further confirmed the formation of a protective film on the carbon steel surface.

Abstract

Laccase was immobilized on a novel conductive polyvinyl alcohol (PVA)/chitosan (CS)/multi-walled carbon nanotubes (MWNTs) composite nanofibrous membrane, Its stabilities and catalytic activity for diclofenac degradation were comprehensively investigated. Laccase was covalently immobilized on the surface of PVA/CS/MWNTs nanofibrous membranes with an average fiber diameter of 100-200 nm. Both enzyme loading and activity retention of the immobilized laccase were found to be significant higher on the nanofibrous membranes with MWNTs (907 mg laccase/g membrane, 76.7% of free laccase) than those without (862 mg laccase/g membrane, 63.5% of free laccase). Immobilized laccase on the PVA/CS/MWNTs nanofibrous membranes exhibited high stabilities, reuse capabilities and removal efficiency for diclofenac. Cyclic voltammetry measurements demonstrated that MWNTs enhanced the electrochemical capacitance of the nanofibrous membrane. It suggests carbon nanotubes may play a significant role on the enhancement of laccase activity immobilized on the nanofibers by improving electron transfer between the enzyme and substrate molecules.

Abstract

Effective deposition of MOFs on "inert" solid surfaces is very challenging. In this work, we found that polydopamine, which can be facilely and tightly formed on any types as well as any forms of solid surfaces, could be used as an effective nucleation center for MOF deposition. Based on this finding, various MOFs were successfully deposited onto nanofibrous polymer membranes, especially the commercially available "inert" ones, affording hierarchically structured porous films.

Abstract

Chitosan (CS)/poly(vinyl alcohol) (PVA) nanofibrous membranes have inherently poor mechanical strength. To improve the mechanical strength of these membranes, nanocrystalline cellulose (NCC) prepared by a simplified method was added to the former system. The results showed that the tensile strength of the membrane with 5% NCC addition was 370% higher than that of the membrane without NCC. Horseradish peroxidase (HRP) was immobilized on the membrane through covalent binding with HRP previously activated with 1,1'-carbonyldiimidazole, and the maximum enzyme loading was approximately 384 mg g(-1). The physical, chemical properties of immobilized HRP and its application in 3,3 ',5,5 '-tetrabromobisphenol (TBBPA) removal were examined. The results showed that HRP immobilized on CS/PVA-NCC membranes showed greater stability and reusability than free HRP and the membrane without NCC. The former also exhibited an effective performance (95.9% removal, 3 h) for TBBPA removal under the optimum conditions (pH 7, 35 degrees C). The results showed that HRP immobilized on NCC-incorporated CS/PVA membranes could be used to remove brominated flame-retardants, especially TBBPA from wastewater. Thus, these membranes have potential industrial applications.

Abstract

Nepal, an underdeveloped country with one of the lowest energy consumption in the world suffers from chronic energy shortage. To meet unquenchable demand of energy, the country spends large amount of money to import fossil fuel and electricity. Urban centers of Nepal have emerged as the main energy consumers and largest green house gas (GHG) emitters due to increasing urbanization and changing lifestyle. Government owned utility company has failed to supply increasing demand of electricity and have resorted to long hours of rolling blackout. Use of solar power technologies can help mitigate the blackout problem as Nepal receives good solar insolation. Despite having good potential for photovoltaic solar power (PSP), its adoption is limited to rural areas due to lack of government support and higher cost. This article analyzes the electricity shortage problem and assesses the feasibility of rooftop PSP in urban areas. The assessment analyzes problems and shortcomings of current system and recommends policy changes to increase use of rooftop PSP. (C) 2014 Published by Elsevier B.V.

Abstract

The corrosion inhibition properties of a combination of polyamidoamine dendrimers and sodium silicate for carbon steel in soft water has been examined and characterized by weight loss measurements, Tafel polarization, electrochemical impedance spectroscopy (EIS), energy-dispersive X-ray spectroscopy (EDS) and atomic force microscopy (AFM). The results show that this environmental friendly corrosion inhibitor at relatively low dosages had a good inhibition effect on the carbon steel corrosion in soft water. The adsorption of a combination of polyamidoamine dendrimers and sodium silicate obeys a Langmuir adsorption isotherm. Potentiodynamic polarization studies show that the corrosion inhibitor was a mixed inhibitor. EDS determined the nature of the adsorption layer on the steel surfaces, and AFM further confirmed the formation of a protective film on the carbon steel surface.
