Abstract

<p>This paper deals with nonconventional approaches to multicomponent spectrophotometric analysis consisting of (i) simultaneous or consecutive addition of several nonselective reagents in the multicomponent determination of metal ions, and (ii) the use of absorbance data which have been measured at different pH values or in different experimental conditions and subsequently combined into a single data set, evaluated by the partial least squares method. The following multicomponent mixtures of metal ions with reagents were examined: Co<sup>2+</sup> and Fe<sup>3+</sup> with nitroso-R-salt and 1,10-phenanthroline; Co<sup>2+</sup>, Cu<sup>2+</sup> and Fe<sup>3+</sup> with nitroso-R-salt and zincon; Co<sup>2+</sup>, Cu<sup>2+</sup> and Zn<sup>2+</sup> with nitroso- R-salt and zincon; and Cu<sup>2+</sup>, Zn<sup>2+</sup> and Ni<sup>2+</sup> with zincon and PAR. The average relative error of determination was 2% (two metal ions) and 5% (three metal ions). Cu<sup>2+</sup>, Zn<sup>2+</sup> and Ni<sup>2+</sup> were also quantitated in ALPAKA alloy with relative errors of 4 - 9%.
