Removal of copper ions from aqueous solutions using poly(vinylbenzyl chloride)

Poly (vinyl benzyl chloride) (PVBC) was synthesized through Reversible Addition-Fragmentation Chain Transfer (RAFT) polymerisation technique utilizing monomer, vinylbenzyl chloride (VBC), 4-cyano-4 (phenyl-carbonothioylthio pentanoic acid) (CPADB) as RAFT agent and 4,4'-Azobis (4-cyanopentanoic...
