摘要：

In this paper, the comparison of activated carbon fiber (ACF) felt and graphite cathode suggested H2O2 might effectively be electrogenerated from O-2 reduction on the large surface area ACF felt cathode. this was more adaptive for electro-Fenton process. The removal of color and total organic carbon (TOC) from simulated dye wastewater containing Acid Red 14 (ARIA) was experimentally investigated using electro-Fenton reaction with ACF cathode. After 360 min of electrolysis and under the operation conditions of 0.36 A current, 1 mM Fe2+ at pH 3, 70% TOC was removed as well as complete decolorization occurred. The effect of Fe2+ ion concentration and applied current were also studied in detail in the experimental runs. (C) 2004 Elsevier Ltd. All rights reserved.
