Bisphenol A (BPA) was found as an important kind of endocrine disrupter chemicals in environmental protection and analysis. In the present paper, BPA in wastewater was extracted electrochemically on the ferric hydroxide nanoparticle modified carbon paste electrode with an isotherm of Weibull growth function, and determined by differential pulse voltammetry under the optimal experimental conditions. The extraction was controlled electrochemically by the redox stages of the extractant, called electrochemical solid phase nano extraction. A sensitive, selective, and convenient electrochemical method for the determination of BPA was developed based on the extraction with the detection limit of 2.0´10-8 mol/L in the concentration range of 2.0´10-8 ~5.0´10-4 mol/L. The equal amounts of phenols do not interfere with the determinations. The method was successfully applied to the determination of BPA (94.00±4.5 mM) in wastewater sample.
