摘要
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.
