报道了十二烷胺萃淋树脂在弱酸性体系中对银的静态分配系数及温度、树脂用量等对吸附银的影响 ,测定了树脂吸附银的饱和容量及树脂的含氮量 ,由此确定萃合物的组成比 ,并用等摩尔系列法、斜率法、红外光谱等方法探讨了该树脂吸萃银的组成 .在此基础上 ,对银的柱上操作进行了研究 ,并将此方法应用于实际样品的分离富集 The influence of the static partition coefficient of silver, the temperature and the amount of the resin on the adsorption of silver in the weak acid system were reported. The saturated capacity of the resin adsorbed silver and the nitrogen content of the resin were determined, The composition ratio of the complex, and the equimolar series method, the slope method, infrared spectroscopy and other methods to explore the composition of the resin extracted silver.On this basis, the operation of the silver column was studied and the application of this method In the actual sample separation and enrichment
