Abstract: | A simple and new simultaneous spectrophotometric method is proposed for the analysis of a three-component system containing
Cu(II), V(V) and Fe(III) without separation using 2-hydroxy-1-naphthaldehyde benzoylhydrazone (OHNABH). The reagent reacts
with all the three metal ions at pH 5, forming soluble colored species in 30% DMF. The physico-chemical characteristics, statistical
analysis and application of the method for the analysis of complex materials are reported. The effect of diverse ions and
the stoichiometry and stability constants are also studied.
