摘要: 本文基于干扰系数校正法,提出一种新的校正元素间相互干扰的方法——逐步逼近校正法,以及相应的计算机软件系统。对复杂体系中元素间相互光谱干扰和元素“自身”非光谱干扰进行校正,获得了良好的结果。

Abstract: Various interelement interferences usually exist in the analysis of complex, multi- component samples by ICP-AES.The problem is how to look for an ideal course to correct them. Anew method named "Successive Approximation Correction Method" (SACM) is advanced in this paper. SACM is based on K-coefficient correction method, and can be described with the equation  Good results, whether major or trace elements, can be gained by the use of SACM. In the article SACMis proven, checked and evaluated.
