发射光谱粉末法直接分析的困难问题之一是元素激发强度依赖于分析样品的基体组成。因此,对于用高比例的“缓冲”化合物和待测试样混合来进行光谱直接测定的通用方法研究,许多作者进行了大量工作。同时,也有不少作者专门探索缓冲剂的效率问题。Decker 和 Eve 对缓冲剂的效率作了比较系统的研究。他们考察了不同缓冲化合物对电弧温度、电极温度、蒸发速度、电弧漂移等的影响,分别研究了阳离子和阴离子的不同效应。在阳离子的研究中,他们认为,虽然电极温度和缓冲化合物的沸点之间没有关系,但电极温度的峰
One of the difficult problems in the direct analysis of emission spectroscopy powder method is that the elemental excitation intensity depends on the matrix composition of the analyzed sample. Therefore, a great deal of work has been done by many authors on the general methodological study of direct spectroscopic determination by mixing a high proportion of “buffered” compounds with the sample to be tested. At the same time, there are many authors who specialize in exploring the efficiency of buffers. Decker and Eve made relatively systematic studies on the efficiency of buffers. They examined the effect of different buffer compounds on arc temperature, electrode temperature, evaporation rate, arc drift, etc., and studied the different effects of cations and anions, respectively. In cation studies, they concluded that although there is no relationship between the electrode temperature and the boiling point of the buffered compound, the peak at the electrode temperature
