摘　　要：以苯乙烯为单体,1,4-二氯甲氧基丁烷和硫代氨基脲为原料合成了聚苯乙烯硫代氨基脲螯合树脂。采用红外光谱法、扫描电镜、X射线光电子能谱对其结构及元素组成进行分析。测定了该螯合树脂的吸附性能,结果表明该螯合树脂对Mn2+、Cd2+、Hg2+、Pb2+的吸附容量分别为16.25、14.23、9.93和11.95mg·g-1。A kind of chelating resin which is called polystyrene N-aminothiourea chelating resin was synthe-sized using styrene, 1,4-dichloro-methoxybutane, thiosemicarbazide as raw meterials.The structure and elements were analyzed by infrared spectroscopy, scanning electron microscopy（SEM）, X-ray photoelectron spectroscopy.The adsorption performance of the polystyrene N-aminothiourea chelating resin for heavy metal ions Mn^2 ＋、Cd^2 ＋、Hg2＋and Pb2＋were investigated. The adsorption capacity of polystyrene N-aminothiourea chelating resin for As^5＋、Cd^2＋、Hg^2＋and Pb^2＋are 16.25、14.23、9.93 和 11.95mg·g^-1 respectively.
