Rapid, selective, more sensitive and well improved spectrophotometric determination methods were developed for low prevailing economically important metals (Zn, Al, Th U, Zr and some toxic metals (Cd , Cr, Ni, Pb) in the presence of surfactants. Suitable chromogenic reagents were used for these determinations. A series of experiments were performed for optimization of important parameters regarding the ternary complexes of the selected metals, organic reagent and surfactants.The reported methods were successfully applied for determination of selected metals in water samples,...
