ABSTRACT
The chemical contaminations of wide range of toxic derivatives in water, in particular heavy metal ions and dyes is a serious environmental problem owing to their potential human toxicity. Therefore, there is a need to develop technologies that can remove toxic pollutants from the wastewater. Adsorption is one of choices used for treating industrial effluents and a useful tool for protecting the environment. In particular, adsorption on synthetic, natural polymers and their derivatives is known to remove pollutants from water. The importance of the synthetic polymers has increased due to their high selectively, stability at elevated temperature and sensitivity to the high concentration of ions. One of the major applications of epoxy and its many derivatives is based on its ability to bind strongly heavy and toxic metal ions. This study will focus on the synthesis of two types of polymers, the first one was carried by suspension polymerization of epoxy resin, methyl methacrylate [MMA] and divinyl benzene [DVB] mixtures which have been modified though epoxy functions in two steps: [i] by treating with polyamine and [ii] by subsequent reaction with potassium chloroacetate. The second type which is a new low cost adsorbent was prepared by modified polysaccharides for example resin was polymerized epoxy resin and cross linked starch mixtures in two steps; [i] by treating with polyamine and [ii] by subsequent reaction with potassium mono chloroacetate, that to increase the efficient sorbet for removal of Cu[II] and Ni[II] ions
