摘要
研究了氯化甲基三烷基铵（Ｎ２６３）萃淋树脂在Ｃｌ－介质中吸附Ａｕ（Ⅲ）的性能．就酸度、Ｃｌ－浓度、温度对吸附过程的影响及吸附动力学进行了实验，发现该树脂的萃金性能优良，吸附容量大于２００ｍｇＡｕ（Ⅲ）／ｇ干树脂．通过动态实验得到了上柱、洗脱过程的最佳条件．还对实际含金样品的浸出液进行分离、分析，获得了满意的结果．
The properties of adsorption of Au(Ⅲ) in Cl - medium with N263 levextrel resin are studied. The effects of acidity,Cl - concentration, temperatures on adsorption processes as well as adsorption kinetics are tested. Based on column means, the optimum conditions for feeding and elution are obtained. This method has been used in the separation and determination of real samples containing Au with satisfactory results.
