| Abstract: | Cationic 2-hydroxypropyl trimethylammonium chloride chitosan(HTCC) was prepared by orthogonal experiment,and the optimum dosage of HTCC for kaolin suspension was determined according to turbidity removal efficiency.Removal rate of the turbidity by HTCC combined with different molecular weight PAM was investigated,and its best composite ratio of HTCC and PAM was determined as 16.67: 1.For original water of 98 NTU turbidity,the turbidity removal rate reached above 96% and residual turbidity less than 4 NTU by... |
