Spectrophotometric Determination of Ni2+, Co3+, Fe2+, Cu2+ Concentrations with 1-(2-Pyridylazo)-2-Naphthol in Aqueous-Micellar Medium Based on two Intensive Parameters
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-one-dimensional processing. Determination of Ni2+, Co3+, Fe2+, Cu2+ ion concentrations with 1-(2-pyridylazo)-2-naphthol in aqueous-micellar medium on two-dimensional absorption spectra of wave length by pH coordinates were performed.
