Partial Least-Squares Method for Measuring of Coexisting Terbium, Gadolinium and Erbium

GUO Chun-Xiao , DUAN Yi-Xiang, DAI Guo-Zhong, JIN Qin-Han GUO Chun-Bao(Dept. of Chem. Jilin Univ. , Changchun,130023) (JilinUniv. of Technology)  
Partial least-squares method is applied in quantitative determination of multi-component mixture of rare earth by UV spectrophotometry. The accuracy of calculation is studied by changing the ranges and intervals of wavelength. The results show its superiority to other numerical methods.
