| Abstract: | It's discussed several synthetic reaction parameters affecting graft copolymerization of acrylamide and starch which utilized Ce(Ⅳ )/HON3 as the initiatior system in the paper.The optimal conditions were selected,and the graft efficiency of the graft starch reached 94. 9%.The molecule weighe in branch chain was more than 3. 0X×106. The graft starch and PAM (3. 0 ×106)were similar in CODcr removal rate and floe subsidence velocity while being used in treating industrial wastewater. |
