Valorisation of bio-products and their chemical modifications with polymers for Environmental applications

More attention is given to the environmental jobs in particular treating the contaminated waters (dyes and metals ) araised from industrial processes. Indeed, as examples of pollutants present in discharged water, dyes and toxic metals are essential in industrial processes. Their toxicity and non biodegradability, force the industries to remove them before disposal or recycling of wastewater. Adsorption is considered an efficient method for water purification. However, it is required to design efficient materials for the removal of pollutants. As known as one of effective technology for wastewater treatment, adsorption ranks high when the studied adsorbents is proved to be both efficient and recoverable. In this setting, the present project deals with the valorisation of bio-products derived from wastes of eggs for environmental applications. To achieve the target, the first approach consists on the collect of the residual wastes from eggs derived from at least 04 birds of various races. The collected residual wastes of eggs and their internal membranes will be pre-treated prior to application. The bioproducts will be modified by synthetic and natural polymers. The newly synthetic polymers will include various alkyl/aromatic diamines, which include ethylene diamine, o-phenylenediamine, m-phenylenediamine, p-phenylenediamine and/or 2,5-diaminotoluene. The poly(trimesylchloride-co-alkyldiamine) grafted to the bioproducts providing the amide functionality that will be responsible for capturing the pollutants. Natural polymers will include chitosan and beta-cyclodextrin in order to improve the adsorption capacities and consequently preparing green composites. Various techniques will be used to characterize the products from each race: chemical composition, FT-IR investigation, Mechanical behaviour of the membranes, Elemental analysis, SEM features, Thermal analysis (TGA and DSC), surface area, etc. Then, the studied products will be applied for the sorption of pollutants (dyes and toxic metals). The same works will be extended for the valorisation of bioshells and their membranes for various plants (white and red race). The effect of pH, concentration, time, dose, etc. will be investigated and discussed. The maximum sorption capacities will be measured. The kinetic data and the isotherms will be modeled using theoritical equations to conclude on the mechanism. To sum up, the proposed research will exhibit a great contribution to water purification because the availability of pure water is going to be a major problem in the future. Our project is of multidisciplinary nature, and it encloses preparation and characterization to applications.
