摘　　要：以2,6-二氯苯酚（2,6-DCP）为模板分子,2-丙烯酰胺丙磺酸为功能单体,三羟甲基丙烷三甲基丙烯酸酯为交联剂,合成一系列分子印迹聚合物微溶胶（MIPM）。通过平衡吸附实验、底物浓度、温度、p H实验对MIPM的吸附性能进行研究。结果表明,该分子印迹聚合物在水中的最佳应用条件为：在10-25℃、底物浓度为2.8 mg/m L时,其最大吸附容量为241.1 mg/g;振荡时间为110 min时,其最大吸附容量为216.3 mg/g;p H为7时最大吸附容量为114.2 mg/g。A series of molecularly imprinted polymers microgel（ MIPM） for 2,6-dichlorophenol（ 2,6-DCP） are synthesized with 2,6-DCP as template molecule,2-acrylamide propanesulfonic acid as functional monomer and trimethylolpropane trimethacrylate（ TRIM） as crosslinking agent. The adsorption performance of MIPM is evaluated by equilibrium adsorption experiment,substrate concentration,temperature and p H. The results shows that the optimum conditions are as follows： the maximum adsorption capacity is 241. 1 mg/g when the substrate concentration is 2. 8 mg/m L at 10 - 25 ℃,and the maximum adsorption capacity of the molecular imprinted polymer is 110 min,The maximum adsorption capacity is 216. 3 mg/g,and the maximum adsorption capacity is114. 2 mg/g at p H 7.
