| Abstract: | A nonlinear model of multiple components systems was developed and ultraviolet spectra data were analyzed by principal component regression. A method for the simultaneous determination of two components with nonlinear principal component regression was established. The method was applied to the simultaneous determination of benzoic acid and salicylic acid in their mixture. The results by nonlinear PCR method were better than those by linear PCR method. |
