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。
Adsorption of thiazole azo reagent with 1300-Ⅱ adsorption resin to prepare impregnation resin. The relationship between the resin adsorption rate to the reagent and gold and the pH value of the resin were studied. The equilibrium rate and adsorption capacity of gold adsorbed on the impregnated resin were obtained. Based on the experimental conditions, a method of column separation and enrichment of trace gold , Got the satisfactory result.
