本文提出用火焰原子吸收分光光度法测定硅酸铅中的微量元素铜、锰、钴、镍和铬,并探索了样品中可能存在的干扰元素及溶剂介质酸度对测定的影响。找出了原子吸收法测定硅酸铅中微量元素的最佳实验条件和分析方法。在消除各种干扰因素的基础上,采用一次消化样品连续测定五个元素的分析方法,精确度高,速度快。 In this paper, the determination of trace elements Cu, Mn, Co, Ni and Cr in lead silicate by flame atomic absorption spectrometry has been proposed. The effects of interfering elements and the acidity of the solvent medium on the determination have been explored. The optimum experimental conditions and analytical methods for the determination of trace elements in lead silicate by atomic absorption spectrometry were found out. On the basis of eliminating various interference factors, the method of continuously analyzing five elements in one digestion sample is adopted, and the method has the advantages of high accuracy and high speed.
