摘要：

In this paper, the preparation and application of copolymers of 2-acrylamido-2-methyl propane sulfo acid (AMPS) were discussed. The results showed that the copolymers with molecular weight 18.10 million can be prepared. In treating waste water from deinked pulp, the dosage of copolymers was 0.75ppm, the optimum dosage of PAC was 100ppm; dosage of the amphoteric polyacylamide (AmPAM) with molecular weight 11.34 million was 0.75ppm, the optimum dosage of PAC was 75ppm. The removed rate of CODcr was above 70%.
