摘　　要：用1300－Ⅱ型吸附树脂吸附噻唑偶氮类试剂制取浸渍树脂。研究了树脂对试剂和对金的吸附率及其与溶液pH值的关系，求得浸渍树脂吸附金的平衡速率和吸附容量，并在条件试验基础上拟订了柱操作分离富集微量金的方法，获得了满意的结果。The adsorbing resin type 1300- Ⅱ was impregnated with the reagent, 2-(2-thiazolylazo)-5-[(N, N-dicarboxymethyl ) amino] benzoic acid (TADCAB). The relation between the pH value of the solution and adsorption rate of adsorbing resin for TADCAB andthat of impregnated resin for gold was studied. With static method the equilibrium rate and adsorption capacity of impregnated resin for gold was obtained. Based on the conditional test method, the separation and enrichment of microamount of gold with column method was proposed, and satisfactory results were obtained.
