Abstract

The electrochemical behavior of bisphenol A was investigated by voltammetric techniques. The electrochemical oxidation of bisphenol A led to the inactivation of the glassy carbon electrode as the result of the deposition of the electropolymerized films. Although phenolate is oxidized more easily than the neutral phenol, an electropolymerized film of bisphenol A was formedin neutral media rather than in alkaline media. The fouling of the electrode surface by the electropolymerized film was evaluated by monitoring the electrode response of ferrocyanide ion as the redox marker. The electrochemical removal of bisphenol A based on the formation of the electropolymerizedfilm on an anode surface was also attempted using a carbon fiber electrodewith a very large surface area. The high removal efficiency for bisphenol A was obtained in a dilute solution of bisphenol A. The maximum surface coverage (Gamma) of electropolymerized bisphenol A on the carbon fiber was about 2 x 10(-9) mol/cm(2). (C) 2001 Elsevier Science B.V. All rights reserved.
