摘　　要：研究了弱碱性阴离子螯合树脂R502对SO42-溶液中高含量Ni2+的静态吸附和动态吸附情况,考察了pH、温度、接触时间以及SO42-含量等对树脂静态吸附镍的性能影响,动态试验通过改变树脂层高度得出不同的吸附流出曲线,进而分析了该树脂对镍的吸附容量以及有效利用率。结果表明,该阴离子交换树脂对Ni2+最高时的吸附量能达到26 mg.g-1,且具有50%利用率,是一类很具有开发潜力的两性树脂。This experiment used the alkalescent anion chelating exchange resin R502 to remove Ni^2＋ from synthetic aqueous solutions, and the research was carried out in two parts including static adsorption and dynamic adsorption. In the first part, the factors influencing the static ion-exchange adsorption properties, such as pH, temperature, adsorption time and SO42-, were studied. The dynamic part got some different adsorption breakthrough curves by changing the resin column height, and then analyzed the resin＇s adsorption capacity and effective utilization rate. Results demonstrated that the resin R502 had a certain adsorption capacity and utilization rate in the removal of Ni^2＋, and this amphoteric resin was a useful treating material in this area
