【摘要】:Chitosan derived from crab shells,was used to prepare the graft polymer in aqueous solution with acrylamide (AM) and methacrylatoethyl trimethyl ammonium chloride (DMC) as raw materials and ceric ammonium nitrate (CAN) as initiator.The floc-culation ability of the resulting polymer (PCAD) was studied in waste water treatment experiments.Its properties were determined on the
The PEO-grafted cationic polyacrylamide microparticles were synthesized via inverse microemulsion tetrapo-lymerization of acrylamide ( AM ) , acryloyloxyethyl trimethylanimonium chloride ( ADAMQUAT ) , PEO-macromonomer (PEO-A) and N, Af
