Abstract
The electrochemical reduction of phenolphthalein in dimethylformamide solution containing 0.1 mol dm−3 tetraethylammonium perchlorate at the hanging dropping mercury electrode showed an irreversible two-electron voltammetric peak. It was found that the CV peak is diffusion-controlled at low concentrations (⩽0.4 mmol dm−3). At higher concentration (⩾0.5 mmol dm−3) a postpeak was developed besides the diffusion-controlled one which was assigned to the adsorbed depolarizer. Cyclic voltammetric studies indicate that phenolphthalein follows an ECEC mechanism. Convolution and deconvolution potential sweep voltammetry confirm that mechanism.
