| Abstract: | The UV-spectra data of mixture solutions, which consist of α-Naphthol, α-Naphthylamine and 2,7-Dihydroxy-naphthalene, were measured. Number, identities and concentrations of every compound involved are determind successfully by directly using Target Factor Analysis technique. The effects of wavelength range and samplin8 interval selected on the results have been discussed. The averase recoveries are 94.84％ for NAP, 108.29％ for NAA, 101. 66％ for DHN respectively. The results obtained are compared to those by Partial Least Square method. |
