摘要：

Reversible addition-fragmentation chain transfer (RAFT) polymerization was employed to synthesize a well defined block copolymer, Poly(2,4-dinitrobenzaldehyde acryloylhydrazone)-b-N-isopropylacrylamide (PDAH-b-PNIPAM) comprising both thermosensitive block and chemical sensitive block, with specific molecular weight and narrow molecular weight distribution. The thermal sensitive LCST temperature is slightly decrease with the increase of mole ratio of PDAH copolymer block. A detailed examination of the effect of contact time and the concentration of heavy metal ion Cd(II) on the adsorption characteristics was performed. The adsorbent with 10.1% mole ratio of PDAH copolymer block exhibits maximum adsorption capacity. The recovery and recycle investigation indicated that the dual-stimuli sensitive block copolymeric adsorbent showed very good renewability.
