摘要
金（Ⅲ）经树脂吸附并还原、淋洗和解吸以后再按孔雀石绿萃取比色法进行比色分析，可以消除常见干扰元素的干扰。本方法的回收率为９５％，标准相对偏差为±５．０％。本方法较为简便快速，满足工业分析的要求。
The analysis of trace gold Was carried out in this paper by malachite green colormetry after the sample solution being absorbed, reduced, washed and eluted with a column of adsorption reside. Result showed that the disturbance of some common disturbing elements can be removed. The recovery rate of the gold in the process is 95%and its comparative error is±5.0%. This process is easier, quicker and more useful for industrial analysis than common separation processes.
