偏最小二乘（PLS）分光光度法同时测定铁钴铜锌

Spectrophotometric Determination of Fe、Co、Cu、Zn with Partial Least Square(PLS)

本文研究了高灵敏度显色剂ｍｅｓｏ－四（４－磺酸苯基）卟啉（ＴＰＰＳ４）与Ｆｅ（Ⅲ）、Ｃｏ（Ⅱ）、Ｃｕ（Ⅱ）、Ｚｎ（Ⅱ）共显色条件以及应用偏最小二乘（ＰＬＳ）法同时测定四组份的方法，获得满意的结果．本文还定义了未知样品与标准样之间的相关系数Ｑｒ，通过Ｑｒ值的大小预报未知样测试结果的准确性．

pectrophotometric determination of Fe(Ⅲ) 、Co(Ⅱ)、Cu(Ⅱ)、Zn(Ⅱ) with TPPS4 and Partial Least Square(PLS) Method has been studied.The experimental results are satisfactoy.Qr has been defined as a relativeity coefficent of actual and standard samples,by whose values the accuracy can be predicted between actual and sandard samples.
