摘要
将TBP（磷酸三丁酯）纤维相首次应用于选择吸附金（Ⅲ），研究了对金（Ⅲ）的吸附性能，选择了吸附、解吸的最佳条件。在10％的王水体系中，TBP纤维棉对金（Ⅲ）具有吸附速度快，吸附能力强、吸附完全，选择性高等优点，且吸附的金易于解脱。方法适应性强，应用于地质样品类复杂物料中金的分离它集与测定，效果十分满意。
In this paper ,it is presented the results about selective adsorption of Gold(Ⅲ)by thetributylphosphate cotton cellulose (TBP)including the adsorptive characters and the optimum con-ditions for adsorption and desorption of Gold(Ⅲ)in the first tim.In the 10%solution of Chloro-zotic acid, TBP used to adsorb Gold(Ⅲ)has characteristics of rapid, powrful,complete adsorptionand high selection, meanwhile, and of easy desorption with a small volume of eluant.The method can be used to separate, proeconcentrate and determine the Gold (Ⅲ )in the geological samples with a satisfatory results.
