摘要
该方法主要探讨利用元素S易造岩特性及NH4I与试样基体强烈作用生成较活泼金属碘化物,极快加剧电极中样品的反应强度,改变了所有分析元素的蒸发行为,增加了电弧等离子体中各种分析元素的浓度,对高沸点元素钨、钼和中低沸点元素硼、银、锡的蒸发起到较好的缓冲作用,通过多次实验数据证明,精确度和准确度均能够满足分析需要。
By using easy rock characteristics of S element, and active metal iodide generated by NH4I and sample matrix, response intensity of electrode samples has been intensified, evaporation behavior of all ele- ments have been changed, various analytical element concentration in arc plasma have been increased, and evaporation of tungsten, molybdenum with high boiling point and silver, tin, boron with low boiling point have been buffered well. As showed by many experiments, precision and accuracy of this method can meet the need of analysis.
