Degradation of o-chlorophenol from aqueous solution by electro-fenton process

The study explores the utility of the electro-Fenton process for the degradation of o-chlorophenol (o-CP) from aqueous solution. The extent of degradation of o-CP is found to be a function of applied current, electrolysis time, concentration of o-CP and concentration of ferrous ions. Under optimized conditions it is possible to achieve efficiencies higher than 70%. Accelerating the regeneration of Fe2+ ions in the electrolyte determines the efficiency of the process. Addition of goethite as a catalyst in the medium did not significantly improve the process efficiency.
