N_(503)萃淋树脂吸附金的性能及其分析应用的研究

Adsorption of Gold With N,N-Di(Sec-Octyl)Acetamide Levextrel Resin and Its Analytical Application

报道了N,N-二仲辛基乙酰胺(简称N_(503))萃淋树脂的合成方法,用AAS法测定了该树脂对金的吸附速率和等温吸附线,在动态试验的基础上,确定了N_(503)萃淋树脂分离、AAS法测定矿样中微量金的方法。

A synthetic method for N, N-di(sec-octyl)acetamide(N_(503))levextrel resin is described. The rate for the adsorption and the isotherm for the adsorption of AuCl_4^- ion on N_(503)levextrel resin were measured by AAS. Based on the effect of various interfering ions, a column method for the separation and pre-concentration of gold with N_(503)levextrel resin is proposed.
