Combined with iterative target transformation factor analysis, single rare earth element was determined in its mixture. The calculated results show that the average angle between rare earth spectra in one color system(trichloroarsenazorare earths, pH 34) is 45, and that in two color systems(trichloroarsenazorare earths, pH 34, 14) is 215. This technique makes it easy to select the real number of the components in mixtures, and the determination results show dualcolor system method is an effective technique in rare earth mixture analysis.展开更多

But it depended on the con-struction of primitive mixture greatly. The new method that AMDS were replaced by the cal-culated most different spectra(CMDS) overcome this restriction. It was applied in the simu-lated and actual systems and the results were satisfactory.展开更多
