Özet

A new approach based on the use of inductively coupled plasma optical emission spectrometry (ICP-OES) is presented for the quantitative determination of Fe, Co, Mn, Cu, Pb, and Zn in ore samples obtained from the Keban Region, Turkey. A 33 full factorial design with 27 sample runs was used to find the optimal sequential extraction conditions for the analysis of these samples. Under optimized conditions for each step of the sequential extraction procedure, calibration curves for the respective metals were obtained by measuring the absorbance values at 238.2 nm for Fe, 228.6 nm for Co, 257.6 nm for Mn, 327.4 nm for Cu, 220.4 nm for Pb, and 206.2 nm for Zn. The proposed ICP-OES method was successfully applied to the quantitative analysis of real ore samples containing Fe, Co, Mn, Cu, Pb, and Zn. Good agreement was found for the analytical results of these metals.
