过氧化氢对分析元素的干扰效应及其校正

EFFECT OF PERHYDROL ON ANALYZED ELEMENTS AND ITS CORRECTION

在等离子体发射光谱中，过氧化氢对分析元素有一定的干扰，并对信号稳定性有一定的影响。铟内参比的使用，对过渡族元素和Ⅰ、Ⅱ主族有了很好的补偿，而对Ⅲ、Ⅳ、Ⅴ、Ⅵ主族元素，这种干扰也基本上得到了校正和校正的研究。

Perhydrol can affect the intensities of analyzed elements. With increment of perhydrol concentration, the intensities of the analyzed elements will degrade. By using of internal reference element, the effect could corrected.
