Özet
In this work, the electrochemical behavior of 4-(2-pyridylazo)resorcinol (PAR) azo dye was studied in Britton-Robinson (BR) buffer (pH 2.0-12.0) media by employing square wave voltammetry (SWV), differential pulse polarography (DPP), direct current polarography (DCP) and cyclic voltammetry (CV) techniques. From the polarographic and voltammetric results, the electrochemical reaction mechanism of the azo dye has been proposed. At the same time, the electrochemical behavior of the copper(II) complex with PAR was investigated by using SWV in 0.1 M KNO3 supporting electrolyte. SWV behavior of Cu(II)-PAR complex at different metal and ligand concentrations have been determined in KNO3 supporting electrolyte media. The metal:ligand molar ratio and stability constant of the Cu(II)-PAR complex were determined to be 1:2 and 5.42x10(10), respectively.
