摘　　要：氯甲基化聚苯乙烯与谷氨酸(Glu)胺解反应合成聚苯乙烯-谷氨酸螯合树脂(下称Glu树脂),通过红外光谱表征树脂结构,测定其树脂的比表面积和孔结构等数据,并研究该树脂对Pb^(2+)和Hg^(2+)的静态和动态吸附性能,结果表明Glu树脂对Pb^(2+)和Hg^(2+)的吸附为55.15 mg·g-1和57.73 mg·g-1.A novel polystyrene chelating resin supported glutamic acid was synthesized via the amination reac-tion of glutamic acid with chloromethylated polystyrene . The obtained resin （ Glu ） was characterized by Fourier transformation infrared spectra. The surface area and pore structure of the Glu are determined. The results show that the adsorption of Glu resin for Hg2＋ and Pb2＋ was 55. 15 mg·g-1 and 57. 73 mg·g-1 , respectively.
