摘要：

In this study, an acid and alkali resistance cationic polyacrylamide flocculants (P(AM-MAPTAC)) was synthesized through copolymerization of acrylamide (AM) and methacrylamido propyl trimethyl ammonium chloride (MAPTAC) by innovative ultrasonic initiation technology. The structure and thermal decomposition property of the obtained polymer were observed through FTIR and TG/DSC measurements respectively. The dewatering performance of P(AM-MAPTAC) was also evaluated by measuring the supernatant residual turbidity (RT), moisture content of the filter cake (FCMC), and chemical oxygen demand (COD) removal rate of the sludge. The RT, FCMC, and COD reached 14.80 NTU, 83.72 %, and 66.8%, respectively, at 40 mg L-1 of P(AM-MAPTAC) and pH of 10.0. Furthermore, P (AM-MAPTAC) showed good acid and alkali resistance, and had better application value.
