Electrochemical reduction of p-aminoazobenzene on glassy carbon electrode

The electrochemical reduction of p-aminoazobenzene was investigated on glassy carbon electrode in aqueous methanolic solution of less acidic and alkaline pII using voltametry techniques. Single wave was observed both at pH 3.0 and in alkaline pH conditions. Cyclic voltametric data showed that the reduction process was kineticly controlled irreverisible process at pH 3.0 and diffusion controlled irreversible process at alkaline pH. Product analysis of the preparative electrolysis experiments confirmed that the reduction was two electron transfer process.
