摘要
本文研究了以铬天青 S 为显色剂,用分光光度-CPA 矩阵法同时测定 Ca(Ⅱ)、Mg(Ⅱ)、Fe(Ⅲ)的最佳条件,进行了测定波长的选择,用于合成样品分析,取得满意的效果。
The optimum conditions for simultaneous determination of Ca,Mg,and Fe were investigated by speetrophotametric-CPA matrix method.The choice of determination wavelength was carried out,This method was applied to the determination of synthetic samples with good results.
