Abstract
A method for the simultaneous spectrophotometric determination of the cobal t(II) and nickel(II) based on formation of their complexes with pyrolidine and carbon disulfide is proposed. The complexes was extracted with p-xylene . An artificial neural network (ANN) model was used to analyze the mixture spectra. The limit of detection for Co(II) and Ni(II) were 0.005 and 0.006 mug/ml, respectively. This procedure allows the simultaneous determination of the cited ions in alloy and synthetic samples. Good reliability of the d etermination was proved. (C) 2001 Elsevier Science B.V. All rights reserved .
