摘　　要：合成以氯甲基化聚苯乙烯为骨架，以4-氨基-3，5-二甲基-1，2，4-三唑为功能基（AMT）的新型三唑螯合树脂AMTR，讨论了酸度、时间、浓度等因素对树脂吸附Au（Ⅲ）的影响，另对树脂的吸附选择性及洗脱性能加以说明。Triazole chelating resin (AMTR) containing 4-amino-3, 5-dimethy-1,2, 4 - triazole (AMT) as the functional group was synthesized by reaction of macroporous chloromethylated polystyrene with AMT. The structure of resin was characterized. The effect of contact time, acidity of and concentration of metal ion on sorption properties of the resin for Au(Ⅲ) were determined. Selectivity and elution properties of resin have also been discussed.
