Online published on 24 December, 2019. Abstract Spectrophotometric study about ion-pair association complex of Mn(VII) as MnO4−by 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). Top Keywords Cloud point extraction, Liquid ion exchange, Manganese (VII). Top | |
