本文报道了金（Ⅱ）的反相萃取柱色层新体系及其应用，以聚四氟乙烯为载体，磷酸三丁酯（ＴＩＰ）为固定相，在１．５ｍｏｌ／ＬＨＣ１介质中定量萃取层析金（Ⅱ）。该方法简便、快速，再现性好，柱再生方法简便。
In this paper, a novel reversed-phase extraction column system for gold (Ⅱ) and its application were reported. Polytetrafluoroethylene (PTFE) as support and tributylphosphate (TIP) as stationary phase were used to quantitatively extract layer Analysis of gold (Ⅱ). The method is simple, rapid and reproducible, and the method of column regeneration is simple and convenient.
