| Abstract: | The effect of reaction temperature and the concentration of monomer and initiator on graft copolymerization was studied in inverse emulsion with starch and acrylamide as raw material.And the flocculating properties of resultant were investigated.The results showed that the influences of reaction temperature,monomer and initiator concentration were prominent and the resultant can flocculate the granulometric suspended solid of the sewage and reach the purpose of flocculating by settling the macroaggregates. |
