| Abstract: | The electroanalytical characteristics of 5-(5-chloro-2-pyridylazo)-2,4-diaminotoluene were investigated by various kinds of electrochemical methods.The number of electrons(n) involved in electrode reduction, diffusion coefficient(D)and standard rate constants for electron transfer(K_(?))were determined.Adsorptivity of the reagent with electro--activity on the dropping mercury electrode was investigated.A possible mechanism of the electrode reduction was proposed, and was also verified experimentally.In the meanwhile, ac d dissociation constant of the reagent was determined by spectrophotometry. |
