摘　　要：测定了聚酯基硫脲树脂对银离子的吸附容量,讨论了吸附时间、溶液酸度,温度及银离子初始浓度等因素对其吸附性能的影响,并对吸附动力学和热力学进行了研究。结果表明,树脂对Ag(I)的吸附遵循G.E.Boyd液膜扩散方程和Langmuir等温式,且吸附为吸热过程。The adsorption capacity of Ag（I） on polymeric ester thiourea resin have been determined, the adsorption performances for Ag（I） were studied under different adsorption time, solution acid, ion concentration and temperature. The result showed that the adsorption data fit the G E. Boyed equation and Langmuir adsorption isotherm as well, and the adsorption behavior was a type of endothermic adsorption.
