摘要：

A procedure for the resolution of simultaneous kinetic processes based on the application of factor analysis to a matrix constructed from spectrophotometric data provided by a diode array detector is proposed. The three possible combinations of formation and disappearance kinetic processes involving two analytes are investigated. First, application of principal components analysis to the spectrophotometric data allows the number of simultaneous kinetic processes involved to be determined and hence the spectra and kinetic curves of the individual components to be reconstructed without their prior knowledge. The proposed procedure was satisfactorily applied to kinetic data simulated from Gaussian and real spectra of the Co(II) and NI(II) complexes of 4-(pyridyl-2-azo)resorcinol (PAR).
