摘要： 以聚氯乙烯为大分子骨架，经三乙烯四胺胺化，再与双丙酮丙烯酰胺(DAAM)发生Michael加成反应，合成了多胺-双丙酮丙烯酰胺修饰的聚氯乙烯树脂(DAAMPV)，探讨了合成树脂对4-氯苯酚的吸附性能. 结果表明，合成树脂对4-氯苯酚的吸附符合Freundlich等温式，吸附过程符合二级动力学模型，其二级速率常数在25和30℃时分别为5.38和9.04 mg/(mg×min). 25℃下对4-氯苯酚的吸附量为45.2 mg/g，去除率可达97%以上，用无水乙醇或4% NaOH可将吸附的4-氯苯酚洗脱.

Abstract: Polyamine-diacetone acrylamide modified PVC resin was synthesized through amination and Michael addition reaction with PVC as support. Adsorption properties of the resin to 4-chlorophenol were studied. The experimental results showed that the adsorption isothermal process accorded with Freundlich model. Its adsorption kinetic curves obeyed a pseudo-second-order rate equation, the rate constant was 5.38 and 9.04 mg/(mg×min) at 25 and 30℃, respectively. The adsorption capacity was 45.2 mg/g at 25℃ and removal rate of the resin for 4-chlorophenol was more than 97%. 4-Chlorophenol adsorbed on the resin could be eluted with anhydrous alcohol and 4% NaOH solution.

Key words: polyamine, PVC resin, Michael addition reaction, adsorption, diacetone acrylamide, 4-chlorophenol
