原子发射光谱分析以其所具有的独特优点,成为地质、冶金等部门重要的测试手段之一。但由于影响因素较多,使该法的应用范围受到一定的限制,其中最重要的影响因素就是基体效应。因此,对于不同的试样就要采用不同的标准系列,这给分析工作带来许多不便。为抑制或减小基体效应的影响,前人在这方面已进行了广泛的研究。本文的目的是为寻找合适的电极形状、缓冲剂和垫底剂种类来改变待测元素的蒸发行为和控制电弧温度的波动,使之抑制或减小基体成分变化的影响,提高测定的精密度和准确度,以适应于不同类型的岩石和矿石分析,这在实用上是很有意义的。
Atomic emission spectroscopy has its own unique advantages, as geology, metallurgy and other departments one of the important test methods. However, due to many influencing factors, the scope of the application of the law is subject to certain restrictions, of which the most important factor is the matrix effect. Therefore, different standard series are used for different samples, which brings many inconveniences to the analysis. In order to suppress or reduce the effect of the matrix effect, previous studies in this area have been extensively studied. The purpose of this paper is to find the suitable electrode shape, buffer and primer type to change the elemental evaporation behavior and to control the fluctuation of the arc temperature so as to suppress or reduce the influence of the change of the matrix composition and to improve the precision and Accuracy to suit different types of rock and ore analyzes makes sense in practical terms.
