| Abstract: | The colour reaction of Nb and Ta with 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (5-Br-PADAP) in the presence of tartaric acid is sensitive, but it is difficult to obtain the true absorption spectra of each component in the mixed system. By applying a mathematical method-factor analysis, the measured absorption spectra of the mixed system of Nb and Ta with 5-Br-PADAP were investigated, and the concentration of Nb and Ta in the mixed system could be simultaneously determined. |
