In this paper, the principal component analysis method has been proposed for simultaneous determation of Cu(2+), Zn(2+), Cd(2+), Mn(2+), Fe(3+) by treating with the overlapping UV-absorption spectra of these metal complexes, which were formed by reacting with the chromogenic reagent 5-Br-PADAP together with OP surface active agent. The results of the artificial mixture samples obtained by the proposed method are satisfactory.
