Preparation of Ampholyte Polymeric Nanocomposites Using Gamma Radiation for the Removal of Some Radionuclides

Abstract

Synthesis of ampholyte nanocomposite polymers as environmentally friendly adsorbents is highly demanded in the field of adsorption of radionuclides. In this work, the following ampholyte nanocomposite polymers were successfully synthesized using gamma radiation for initiating the grafting of monomers onto natural polymers in the presence of Fe2O3 as a magnetic nanoparticle (MNPs) by template polymerization technique., • P (N,N-diallyldimethylammonium chloride-acrylamide) carboxymethyl cellulose sodium salt/ Iron(III) oxide • P(N,N-diallyldimethylammonium chloride- sodium acrylate) carboxymethyl cellulose sodium salt/Iron(III) oxide • P(vinyl imidazole-sodium acrylate)carboxymethyl cellulose sodium salt/Iron(III) oxide • P (N,N-diallyldimethylammonium chloride-acrylamide) sodium alginate/ Iron(III) oxide • P(N,N-diallyldimethylammonium chloride- sodium acrylate) sodium alginate /Iron(III) oxide • P(vinyl imidazole- sodium acrylate) sodium alginate/Iron(III) oxide The influence of reaction conditions, such as concentration and composition of monomers, polymer, crosslinker (NMBA) and MNPs concentration, on the grafting efficiency and swelling degree were studied. The structural characteristic of ampholyte nanocomposite polymers was confirmed by means of FTIR, SEM, and TGA. The adsorption behaviors of ampholyte nanocomposite polymers toward 60Co and 99mTc radionuclides
