Syntheses of amidoxime polyethylene resin for selective Uranium (VI) adsorption

Uranium is a major element in the management of spent nuclear fuel (SF) or radioactive wastes, and selective separation of U has been one of research targets. For the separation of U from fission products (FP) in a SF, usually, a solvent extraction or an ion exchange technology has been usually used in an acid medium. In the case of ion exchange method, anion exchanger has been used. However, recently, some absorbents containing amidoxime functional group selective for the U have been designed and synthesized. Therefore, new adsorbent capable of selective sensing U over FP in a carbonate solution are now highly demanded. So, in this study, total synthesis of the polymer-amidoxime derivatives, divinylbenzene-amidoxime (DVB-AO) and polyethylene amidoxime (PE-AO) have been developed and the desired final products were successfully synthesized
