Synergistic thallium and iodine memory-based cryogel traps for removing thallium and iodine ions

Abstract

Both recovery and effective removing of radioactive thallium and iodine are important subject to protect human health and the environment. In this study, we have studied synergistic and cost-effective cryogel based sorbents by combining the high selectivity adsorption ability of MIP and the high porosity of cryogels. For thallium-imprinted cryogel; N-methacryloyl-(l)-cysteine (MAC) has synthesized, MAC has complexed with thallium ion and polymer cryogel has been prepared. For iodine-imprinted cryogel; MAC-thallium has complexed with iodine; and polymer cryogel has been prepared. Then, the adsorption, desorption, selectivity and reusability experiments have been carried out.
