Synthesis of bi-functional chelating sorbent for recovery of uranium from aqueous solution: sorption, kinetics and reusability studies

A bi-functional chelating sorbent is synthesised by introducing two different functionalities (amine and amidoxime groups) subsequently on the surface of an earlier synthesized cross-linked poly-acrylonitrile beads. The cross-linked base polymer beads are normally synthesised through suspension polymerisation using acrylonitrile and styrene as monomers and divinyl benzene as cross-linking agent. The bi-functionality is introduced by amination of...
