由于碳酸岩样品光谱背景很深等原因,在一般条件下,光谱灵敏度比硅酸岩低得多,而这类样品中,按化探要求需要测定的元素含量极微,这就对分析测试工作带来一些困难。为此,我们对碳酸岩中锂、锡、铋、银、铅、锌、铜等微量元素的分析进行了一些试验研究,制定了同时测定多元素的光谱定量分析流程。试验确定以硅粉、碳粉、硫粉、过碘酸钾
Due to the deep spectral background of carbonate samples, the spectral sensitivity is much lower than that of silicate under normal conditions. In such samples, the elemental content to be determined according to the geochemical requirements is very small, which is of great significance to the analysis and testing work Bring some difficulties. To this end, we conducted some experimental studies on the analysis of trace elements such as lithium, tin, bismuth, silver, lead, zinc and copper in carbonate rocks and developed a spectrometric quantitative analysis procedure for the simultaneous determination of multiple elements. Test to determine the silicon powder, toner, sulfur powder, potassium periodate
