Polarographic and voltammetric investigations of 8-hydroxy-7-(4-sulfo-1- naphthylazo)-5-quinoline sulfonic acid-nickel metal complex
Özet
The aim of this study is to elucidate the structure of 8-hydroxy-7-(4- sulfo-1-naphthylazo)-5-quinolinesulfonic acid-nickel complex by using square wave voltammetry, differential pulse polarography, (DPP) and direct current polarography (DCP) techniques in Britton Robinson (BR) buffer and KNO 3 media. Two peak potentials have been determined for the nickel-azo complex in SWV, DCP and the ratio of metal-complex has been found to be 1:2 under the experimental conditions.
