摘　　要：本文对浸渍树脂的合成条件进行探究,得到对重稀土离子吸附效果最佳的浸渍树脂。将[A336][P507]与XAD-7树脂混合振荡1h(液固比10:1mL/g),浸渍率最高达60.51%,吸附量为299.8μg/g,基本将溶液中的Dy(Ⅲ)吸附完全。通过扫描电镜、红外表征对浸渍树脂的负载效果与作用机理进行分析。In this paper,the synthetic conditions of impregnated resin are investigated and the impregnated resin with the best adsorption effect for heavy rare earth ions is obtained.By mixing [A336][P507] with XAD-7 resin for 1h(liquid-solid ratio is 10:1 mL/g),the maximum impregnation rate is 60.51%,the adsorption capacity is 299.8 μg/g,and Dy(Ⅲ) in the solution is almost completely adsorbed.The loading effect and mechanism of impregnated resin are analyzed by scanning electron microscope and infrared characterization.
