摘要
本文用偏最小二乘法(PLS)进行多组份光度分析。该法用隐变量矩阵代替吸光度及浓度矩阵,数据处理效果优于经典的多元线性回归法。本文还对多组份光度分析中波长的选择作了研究,提出以吸光系数行列式之值作波长选择判据。实验表明,由此法选择波长是适宜的。将本文提出的方法对Co,Ni,Cu三组份体系进行了分析,获得了较好的结果。
The application of partial least squares method for simultaneous spe-ctrophotometric determination was investigated. A method of wavelength selection was presented. As an example, a method for the determination of Co, Ni and Cu in mixture was given and the experimental results obtained were satisfactory.
