Type: article
Abstract: Results comparison was performed within the terms of multi-component analysis for light absorption arrays processed using the method of consecutive separation of graduation surface (MCSGS), developed by the authors, with other methods of pseudo-onedimensional processing.Determination of Ni 2+ , Co 3+ , Fe 2+ , Cu 2+ ion concentrations with 1-(2-pyridylazo)-2naphthol in aqueous-micellar medium on two-dimensional absorption spectra of wave length by pH coordinates were performed.The results of calculation were compared with calculations by least squares method (LSM), partial least squares method (PLS) and principal component regression analysis (PCA).
