Polarographic and voltammetric investigation of 6'-butoxy-2,6-diamino-3,3'-azodipyridine

Abstract

Voltammetric and polarographic reduction on a hanging mercury electrode in aqueous-ethanol medium was performed for the 6'-butoxy-2,6-diamino-3,3'-azodipyridine by using SWV, DPP, DCP and CV techniques. Electrochemical behaviour of the azo compound has been investigated depending on ethanol-water ratio. From the polarographic and voltammeric data, electrochemical reduction mechanism has been suggested. Adsorption effect of the azo compound was investigated at different pH values. Optimum conditions are given for its polarographic and voltammetric determination. The limit determination using an HMDE was around 2.72 X 10(-9) M for SWV. (c) 2005 Elsevier Ltd. All rights reserved.
