The preparation flocculant of graft copolymers acrylamide with starch using Fe~(2+)/H_2O_2 initiator

LI Shu-peng

Abstract

Graft copolymers of starch with acrylamide was synthesized using Fe2+-H2O2 as initiator.The factors of polymerization to graft copolymerization reaction has been discussed and the flocculating property of the copolymer product was determined using aqueous suspension of kaolin.The optimum conditions were that grafted copolymers in grafted rate 85%,the removal rate of turbidity can reach 80%.
