Abstract:

The electrochemical behavior and the mechanism of methyl orange on tin oxide film electrode were studied by thin layer spectroelectrochemistry. The final products of the reduction of methyl orange are N,N-dimethylphenylenediamine and sodium aminophenyl sulfonate. There are two steps of hydrolytic reactions following the oxidation of the electrogenerated N,N-dimethylphenylenediamine in solution.
