It leads to many health issues ranging from diarrhea, vomiting to life-threatening diseases like cancer, lung/kidney damage. This also affects soil biota/plant growth. Metal-ions have a tendency of bioaccumulation, hence pose a major issue upon entry in the food-cycle. Their removal from water is necessary before use for human/agricultural applications. Different methods reported for metal-ion separation are conventional methods viz. chemical-precipitation, ion-exchange, adsorption, coagulation, flocculation, flotation, electrochemical possess good separation efficiency, but the generation of a secondary pollutant, recovery issues restrict their applicability. Hence, there is a need of reliable techno-economical, environment-friendly, sustainable separation, recovery method. Membrane-based methods viz. reverse-osmosis, nanofiltration, electrodialysis, ultrafiltration has ability to treat water for heavy metal recovery without chemical contamination. Recovered materials can be recycled/utilized further. Among different membrane-based processes, micellar/polymer enhanced ultrafiltration requires chemical addition and affects purity. Electrodialysis, reverse-osmosis, nanofiltration processes require large energy/operational issues. Hence, simple ultrafiltration with membrane modification is preferable as low-energy requirements. This paper discusses details of conventional/advanced methods for heavy metal separation with the fundamental process, parameters, advantages/limitations.

Hence its presence in the effluent is overlooked although it is reported to be detrimental at higher concentrations. Its effect on humans varies from simple dizziness, diarrhea to liver/kidney damage, etc. Various techniques are reported for separation of these toxic pollutants from effluent. This article focuses on development of polysulfone-based membranes with use of additives: polyethylene glycol (PEG) and ZnO nanoparticles (NPs) (nascent and modified with HCl) for separation of copper from effluent by Donnan Exclusion principle. The incorporation of acid treated ZnO NPs in membrane matrix provides surface charge to membrane. This results in repulsive interaction with copper salts from process which retained in retentate as per Donnan exclusion principle. The membrane formed with 40% PSF-0.8% ZnO NPs shows the rejection of copper up to 40%, which raises to 61% when instead of nascent NPs, HCl treated NPs were used. The rejection efficiency of the membrane raises up to 90% when PEG was used along with PSF and ZnO NPs (acid treated). The use of modified NPs in membrane matrix has strong impact on membrane morphology and rejection efficiency. The modification of surface charge properties and morphological distribution of NPs is supported by FTIR and EDX. Further the separation works upon physical distribution of NPs, which would help to maintain the stability properties of PSF based membrane enhancing its applicability in actual process conditions.

PBI membranes possessing basic functionality selectively sorb acid, which is transported to the permeate side by concentration gradient. Transported acid is removed from the permeate side by using stripping agent. The sorption of non-acidic organic (glucose) and inorganic (NaCl) solutes being absent in PBI membranes, they were not transported on the permeate side. This offered high selectivity towards transporting acid. Three structurally different PBIs were evaluated as membrane materials for acid sorption and transport. Effects of variation in operational temperature, concentration and type of stripping solvent were evaluated. A single step process with appreciable acid transport rate coupled with very high selectivity convey promises of 'Chemodialysis' towards its applicability for the separation of organic acids from various industrial process streams (e.g. during production of organic acids by biological routes, which usually involve number of steps and extensive usage of chemicals for their recovery from fermentation broth). Moreover, this process holds additional benefit of low energy requirement, since it works with concentration gradient as the driving force and requires energy only for the circulation of solutions.

A small variation in atmospheric condition has large precursion on agriculture production. Whereas daily temperature variation upto 10 can be observed in several parts of India. This variation can affect crop production adversely. Hence, formation and optimization of polycarbonate based polyhouse is investigated in this work. Further, it was observed that the materials and properties of polysheet would affect temperature and other condition of polyhouse. In current work, the material optimization was investigated and observed that an introduction of UV active nanomaterials provides better climatic control of polycarbonate based polyhouse. Applications of ZnO or TiO2 enhance the absorbance of UV rays from sunlight and resulted in large control on greenhouse environment. This helps to provide enhanced control on greenhouse conditions. The effect of presence of polycarbonate with 0.3% TiO2...
