本文讨论了HPIEC在无机分析方面的应用和某些优化方法在HPIEC中的应用,并提供了一种测定贵金属中重金属杂质的简便快速的方法。本工作主要有两部分: (一)色谱分离条件的最优化 1.以离子交换平衡和溶液平衡理论为指导,结合少量实验确定了一个分离Cu~(2+)、Ni~(2+)、Zn~(2+)、Pb~(2+)、Co~(2+)、Cb~(2+)的较好三元络合洗脱液:酒石酸钠、柠檬酸钠、氯化钠。 This article discusses the application of HPIEC in inorganic analysis and the application of some optimization methods in HPIEC and provides a simple and rapid method for the determination of heavy metal impurities in precious metals. This work has two main parts: (a) the optimization of chromatographic conditions 1. ion exchange equilibrium and solution equilibrium theory as a guide, combined with a small amount of experiments to determine a separation of Cu ~ (2 +), Ni ~ (2+), Zn 2+, Pb 2+, Co 2+ and Cb 2+: sodium tartrate, sodium citrate and sodium chloride.
