中文摘要：

采用沉淀聚合法制备了铅离子印迹聚合物,研究印迹聚合物对Pb2＋的吸附性能,讨论了吸附过程的动力学和热力学特征。结果表明,在20 m L质量浓度10.0 mg/L的Pb~（2＋）溶液中,溶液p H为6、温度为30℃、投加量为120 mg,吸附平衡时间为6 h的条件下,铅离子印迹聚合物对Pb2＋去除率达到98.4%。吸附动力学过程可以采用准1级动力学方程描述。温度对吸附效果有影响,在20℃时,等温吸附过程采用Langmuir模型描述比较合理;在30℃和40℃的等温吸附过程采用Langmuir和Freundlich模型均可进行描述。对吸附热力学参数ΔG、ΔH和ΔS的计算表明,吸附过程是吸热的自发过程。

英文摘要：

The Lead（II） ion imprinted polymer was prepared by precipitation polymerization method, its adsorption property for Pb（II） was studied and the kinetics and thermodynamics of adsorption process were discussed. The result showed that, Pb（II） removal rate could reach 98.4% by adding 120 mg imprinted polymer into 20 m L solution with Pb（II） mass concentration of 10.0 mg/L, and the p H, temperature and adsorption equilibrium time was 6, 30℃ and 6 h, respectively. The adsorption kinetics could be described by pseudo-first-order kinetic equation. Langmuir and Freundlich isotherms were used to fit the adsorption equilibrium data and the adsorption process followed the Langmuir isotherm adsorption mode at 20 ℃. Isothermal adsorption process also followed the Langmuir and Freundlich isotherms modes at 30 ℃ and 40 ℃. Thermodynamic parameters of the adsorption process such as ΔG, ΔH and ΔS were calculated and the results indicated that the overall adsorption process was endothermic and spontaneous.
