Abstract
Electrochemical behavior of alizarin was investigated at carbon paste electrode in 0.2 M acetate buffer solution at pH 3.5 by using cyclic voltammetric technique (CV). Alizarin showed one oxidation peak and two reduction peak between potential range 0 to 1000 mV at scan rate of 50mV/s. The effect of scan rate and concentration was found to be diffusion-controlled electrode process. The electrocatalytic effect of alizarin was dependent on pH. Surfactants effect study showed that the TX-100, a non ionic surfactant has highest electrocatalytic activity towards alizarin.
