摘　　要：基体效应是化学分析中常见的干扰之一,但对其作用机理目前还不清楚。在碱溶酸处理直接用ICP-OES法测定钇和锆的分析中,大量基体进入测定溶液,致使测定结果偏低。本文采用多元统计的方法对测定结果和基体组分含量进行处理,求得了测定误差的一些模型,以评价这类基体效应,并校正测定结果。Matrix effect is one of common interferences in chemical analysis,but its mechanism has not been known.When Y and Zr are determined with ICP-OES a large amount of matrixes get into the determined solution which results in analytical data lower than actual values.Applying multielemental statistical method to the treatment of analytical data and matrix contents,this paper gives some models for determining analytical error in order to evaluate the matrix effect and to correct the analytical error.
