摘要
探讨了原子吸收光谱法测定常量金时,所用的泡塑、硫脲及样品测定时的温度对金分析精密度的影响,在选定条件下,对标样平行测定的相对标准偏差小于7%。
The influence factors on analysis precision, including foam, sulfocarbamide and the temperature, are studied in de- temination of gold of common content by atomic absorption spectrometry. Under the selected conditions, the relative standard deviation to parallel determination of standard sample is less than 7%.
