在发射光谱分析中应用化学反应的方法,由于它具有很低的分析检出限和较高的分析精度等特点,现已在纯物质中的杂质元素分析和矿物原料中的痕量元素分析方面,得到了较广泛的应用。並在反应机理、反应条件和反应剂的选择等方面做了相当多的研究。这种方法的实质是:利用电弧高温使装填在电极孔中的试样物质和加入的化学反应剂之间发生化学反应。反应的结果,试样中的待测元素转变为更易挥发,更易离解的化合物。或者基体元素
Due to its low analytical detection limit and high analytical accuracy, the method of chemical reaction in emission spectroscopy is now used in the analysis of impurity elements in pure substances and trace elements in mineral raw materials , Has been more widely used. And in the reaction mechanism, the reaction conditions and the choice of reactants done a lot of research. The essence of this method is that the high temperature of the arc causes a chemical reaction between the sample substance filled in the electrode hole and the added chemical reagent. As a result of the reaction, the analyte in the sample is converted into a compound that is more volatile and easily dissociated. Or matrix element
