波长回归法分光光度同时测定铝和铁

Simultaneous Spectrophotometric Determination of Al and Fe by Use of Linear Regression

摘要: 本文研究了铬天青S(CAS)/Triton X-100体系用于同时测定铝与铁的显色条件,借助多波长数据线性回归法处理数据,提出了光度测定铝和铁的简便方法,免去了分离手续。

Abstract: A simultaneous spectrophotometric method for the determination of Al and Fe in mixture at pH 6 is proposed on the basis of a study on a Metal/ CAS/Triton X-100 chelating system. A linear regression technique is applied to the analysis of the multicomponen
