本法采用氯化法挥发基体锡,富集杂质,然后用溶液干渣法完成分析。为确定最佳光谱分析条件,我们采用了正交设计法进行试验,确定了狭缝、光栏、光源、激发参数等因素,制定了高纯锡中铅、铜、铋、铁、钴、镍、银、锌、铊、铟、镓、铝、钙、镁、锰、钛、金、镉等18个元素的化学光谱定量分析方法。本法与其他化学分析方法相比较,显示了快速、简便、准确的优点。
This method uses chlorination of volatile matrix tin, enrichment of impurities, and then use the solution dry slag method to complete the analysis. In order to determine the optimal spectral analysis conditions, we used the orthogonal design method to test, determined the factors such as slit, light bar, light source, excitation parameters and so on, and developed the lead, copper, bismuth, iron, cobalt, , Zinc, thallium, indium, gallium, aluminum, calcium, magnesium, manganese, titanium, gold, cadmium and other 18 elements of the chemical spectroscopy quantitative analysis method. Compared with other chemical analysis methods, this method shows the advantages of fast, simple and accurate.
