本文报告光譜分析中氯化物載体对杂貭元素譜綫強度的影响。实驗中观察到各种氯化物均能增強譜綫強度。在电极中,样品与載体均勻混合或分为两层的結果相同。載体用量与杂貭元素譜綫強度間有簡单比例关系。根据实驗数据,可以认为当燃弧后,氯化物載体預先气化,然后与固态的杂貭氧化物发生异相氯化反应,生成易揮发的杂貭氯化物,提高电弧中元素的浓度,从而增強譜綫。
This article reports the effect of chloride support on the spectral line intensities of impurity elements in spectral analysis. Experiments were observed that a variety of chloride can enhance the line intensity. In the electrode, the result is the same if the sample is mixed evenly with the carrier or divided into two layers. There is a simple proportional relationship between the amount of carrier and the spectral line intensities of impurity elements. According to the experimental data, it can be considered that when the arc is burned, the chloride carrier gasifies in advance and then undergoes heterogeneous chlorination reaction with the solid oxide, resulting in volatile chloride and increasing the concentration of elements in the arc, Thus enhancing the spectrum.
