The removal of bisphenol A (BPA) by a novel electro/Fe3+/peroxydisulfate process is reported in this study. The effects of initial pH, electrolyte concentration, Fe3+ concentration, peroxydisulfate (PDS) concentration and current density were investigated. The results indicated that the removal efficiency of BPA declined with the increase of initial pH and electrolyte concentration, but increased with an increase of Fe3+ concentration and current density. The BPA degradation efficiency was improved significantly when the PDS concentration was increased from 1 to 10 mM, but further PDS increase had little effect. BPA was almost completely removed after 60 min reaction and a TOC removal efficiency of 94.3% was achieved when the reaction time was extended to 120 min. (c) 2013 Elsevier B.V. All rights reserved.
