本文叙述了一种四元淋洗液同时分离和测定七种金属离子的色谱条件。探讨了各离子的保留行为与淋洗液pH值和络合剂浓度间的变化规律。方法用于镀铬槽液中金属杂质分析,相对标准偏差小于2.0％,相对误差不超过3.5％。
This article describes the simultaneous separation and determination of seven kinds of metal ions by a quaternary eluent. The variation of the retention behavior of each ion and the pH value of eluent and the concentration of complexing agent were discussed. The method was applied to the analysis of metal impurities in chrome bath, the relative standard deviation was less than 2.0% and the relative error was less than 3.5%.
