Abstract

Spectrophotometric study about ion-pair association complex of Mn(VII) as MnO4by using (4hydroxyphenylazo)-4-Benzennaphthol HPABN as organic reagent shows wave length for maximum absorbance was λmax= 292nm, so the study about determination the optimum condition of extraction shows the extraction method need presence 0.2 M HCl and 100 μg of Mn (VII) as MnO4, so 0.5 mL of TritonX-100, and necessary heating the solution at 80ºC for 20min with existence 0.1 M of NaCl as electrolyte, so that stoichiometry exhibits the most feasible extracted structure of ion-pair complex with 1:1 (organic reagent: MnO4). The research involved many other studies such as interferences, surfactant kinds organic reagents kind so that spectrophotometric determination of Mn (VII).
