Novel biomass-based materials for high efficiency wastewater treatment

Wastewater polluted with heavy metals, organic dyes, oils and other contaminants have hazardous effect on the human being and environment. The shortage in water resources, arising from population increasing, consider a critical problem, especially with increasing demand to pure water resources. Sustainable and environmentally friendly multifunctional biopolymers, such as polysaccharides, were emerged recently for water treatment. A new aspect that will attract more attention in the current project is the use of cellulose nanomaterials which are attractive from the mechanical and surface properties viewpoints, as adsorbents for different pollutants. Their performance is expected to record high adsorption capacity and low cost, comparing with traditional adsorbents. Preparing a new classis of ionic polysaccharides-based materials will be studied in order to increase their capacity for water purification. These materials will arise from the reaction of various polysaccharides, such as cellulose, chitin and alginate with various ionic functional groups. The studying of the adsorption kinetics and isotherms of different water-soluble pollutants from contaminated water will be evaluated in detail. The availability of immobilizing metal oxides on these polysaccharides suggests their using as promising candidate for the photocatalysis which emerged as an environment-friendly wastewater treatment approach technology and facile strategy for degradation of organic pollutants including dyes. It also can be applied in oil/water separation if the hierarchical micro-nano structure and unique chemical compound was constructed by immobilizing metal oxides. Hence, the multifunctional material from polysaccharide for simultaneous removal of insoluble oil and soluble contaminant is also studied.
