Cyclic voltammetric quantification of the amino compounds with special reference to naphthyl amine at various solid electrodes

The voltamatric behavior of some  aromatic amino compound, such as alpha naphthyl amine and beta naphthyl amine was investigated and the method was developed for the simultaneous determination of these compounds. Adsorption of alpha naphthyl amine and beta naphthyl amine at solid electrode such as platinum and gold has been studied using cyclic voltammetry and linear sweep techniques. It was found that pH greatly influences characteristics of naphthyl amine. CV studies with platinum electrode at pH 4 gives second oxidation peak with no reduction peak whereas with gold electrode at pH 3 and 4 alpha naphthyl amine peak gives second oxidation peak with a cathodic peak . The effect of different parameters on the peaks response as supporting electrolyte, pH and scan rate were examined.  Kinetic parameters were also calculated for the compounds.
