研究了用火焰原子吸收法分析高纯铅中痕量钴、镍的测定条件。用盐酸沉淀分离基体铅 ,滤液蒸至小体积挥发多余酸并富集微量元素 ,火焰原子吸收法可测定含量大于 0 3μg/g的钴和大于 0 12 μg/g的镍。用该法测定铅冶炼厂电解精铅成品及半成品中痕量的钴和镍 ,结果满意
The determination of trace cobalt and nickel in high purity lead by flame atomic absorption spectrometry was studied. Lead was separated by hydrochloric acid precipitation. The filtrate was evaporated to a small volume to evaporate excess acid and enrich trace elements. Flame atomic absorption spectrometry was used to determine the cobalt content greater than 0 3 μg / g and the nickel greater than 0 12 μg / g. The method was applied to the determination of trace amounts of cobalt and nickel in finished lead and semi-finished lead from lead smelter. The results were satisfactory
