Abstract:

 

In this study, the electrochemical behaviour of 4'   -halogene-N,N-dimethyl-4-aminoazobenzene derivatives were investigated   using various polarographic and voltammetric methods. The peak potentials of   these derivatives were observed to shift towards negative values with   increase in pH. The standard rate constants were determined with (Laviron   technique) or without (Nicholson and Klingler-Kochi techniques) taking the   adsorption phenomena into account. The diffusion coefficients were   calculated from the cyclic voltammetric data using the method developed by   Garrido. The amount of adsorbed substances (surface excess values) and   transfer coefficients for the electron transfer were also determined. These   compounds can be quantitatively determined between 1 x 10-5 M   to 2 x 10-7  M with DPP.
