| 摘 要： | 偏最小二乘法(PLS)是用于多组份混合体系同时测定的十分有效的统计学方法。本文将PLS法与光度分析相结合,以5Br-PADAP为显色体系同时计算测定了铜、锌、锰,并应用于铸铝样品的分析,都获得了较满意的结果。还用不相容因子(DF)自检分析结果的可靠性。

| Abstract: | The application of the PLS method to simultaneous spectrophotometric determination ofcopper, zinc and manganese in 5-Br-PADAP-OP system has been investigated. The methodgave satisfatory results for the determination of these elements in composite samples and inAl-alloy sample without previous separation. The relative errors are 1.3-9.7%. |
