Abstract

Environmental pollution remains one of the major problems both on the national and international level. One of the most severe problems with respect is the presence of toxic substances such as heavy metal ions, anions in the industrial wastewaters. Heavy metals such as lead, cadmium and copper [1], and different types of dyes in wastewater [2] are known to pose risks to environment and human. Various conventional techniques [3] and advanced oxidation processes have been used for the removal of dyes from wastewater [4]. There is a huge need for developing new, effective and cost-efficient technologies for removal of pollutants from wastewaters. Among many sorptive materials, various forms of synthetic polymers containing complexing molecule, which are abundantly at low cost, have emerged as one of the most important materials for the synthesis of new sorbents [5].The use of high-energy radiations in the grafting and copolymerization processing is known to improve the physicochemical qualities of many polymer products to expand their utilizations. This trend is envisaged to be continuously growing to form a big application field of polymeric products.
