摘要
使用双功能柱离子色谱-柱后衍生-PeakNet软件-紫外可见检测法,探讨了满足Ⅳ水质要求的微量可溶态重金属离子Pb2+、Cu2+、Cd2+、Co2+、Zn2+和Ni2+共存的最佳测定条件。讨论了此条件下,山西区域内高硬度水质中Ca2+、Mg2+离子对上述6种离子同时测定的影响。
In this paper, the optimal conditions on the simultaneous determination of trace heavy metals being dissolved （Pb^2＋ ,Cu^2＋ Cd^2＋ ,Co^2＋ Zn^2＋ and Ni^2＋ ） at vg/L levels were studied, which satisfied IV water quality demand. The metal ions were separated by ion chromatography on a mixed bead ion exchange column and detected by post-colunm reaction and UV/visible spectro-photomet- tic detection and Peak Net software. Furthermore, it was discussed that the Ca^2＋ and Mg^2＋ in the high hardness water from Shanxi interfered with separation and quantitative analysis of the metals for the proposed method.
