摘　　要：以2-丙烯酰胺-2-甲基丙磺酸为功能单体(AMPS),孔雀石绿(MG)作为模板分子,乙二醇二甲基丙烯酸酯(EGDMA)为交联剂,通过自由基交联聚合(RAFT)的方法合成了MG印迹聚合物。将此吸附剂应用于水溶液中阳离子染料的吸附研究,考察了温度、浓度、pH等实验条件对实验过程的影响。通过实验探究,发现此吸附过程更趋向于准二级动力学模型,且符合Langmuir吸附,在吸附时间为为3 h,溶液温度为25℃,pH=7,吸附剂用量为5 mg时,MIP对孔雀石绿的吸附量可达1808.91 mg/g。MG Imprinted polymer was synthesized by free radical cross-linking polymerization(RAFT)using 2-acrylamy-2-methylpropanesulfonic acid as functional monomer(AMPS),Malachite green(MG)as template molecule and ethylene glycol dimethacrylate(EGDMA)as crosslinking agent.The adsorbent was applied to study the adsorption of cationic dyes in aqueous solution.The effects of temperature,concentration and pH on the adsorption process were investigated.Through experimental investigation,it was found that the adsorption process was more in line with the quasi-second-order kinetic model and consistent with Langmuir adsorption.When the adsorption time was 3 h,the solution temperature was 25℃,the pH was 7,and the dosage of adsorbent was 5 mg,the adsorption capacity of Malachite green by MIP could reach 1808.91 mg/g.
