摘要：
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% DME 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.
