An amphoteric metal adsorbent, poly( N -acryloyl- l -histidine)-modified sawdust (SD- g -P(A-His)), is prepared by reversible addition–fragmentation chain transfer (RAFT) polymerization of N -acryloyl- l -histidine from modified sawdust. SD- g -P(A-His) possess imidazolyl and carboxyl groups and sho...
