摘　　要：氯甲基化聚苯乙烯与L-谷氨酸(L-Glu)反应合成了聚苯乙烯系-L-谷氯酸树酯,并测定了红外光谱、残余氯含量、比表面积;结果表明,聚苯乙烯-谷氨酸螯合树脂残余氯含量低,反应完全。并研究了该树脂在不同温度下对苯胺的吸附性能,利用热力学函数关系计算得到了吸附焓、自由能和熵。研究表明其对苯胺有较好的吸附性能。A novel polystyrene microsphere based L-glutamic acid was synthesized via the amination reaction of L-glutamic acid with chloromethylated polystyrene. The structure of the resin was evaluated through analysis of the FT-IR spectrum, remained chloride concentration and BET specific surface area. The experimental data indicated that the chemical reaction of the Glu resin was easier; the residual chlorine content was low. The adsorption isotherms of aniline in solution at different temperatures were studied. Isothermal adsorption enthalpy,Gibbs free energy and entropy were calculated according to thermodynamic equations. The results showed that this polymeric microsphere had strong adsorption to aniline in solution.
