Advanced Chemical Oxidation Of 2,4,6-Trichlorophenol By Using Fenton's Reagent - Dechlorination And Toxicity Reduction, Kuang-Wei (Stone) Chen, Irvine W. Wei

Irvine W. Wei

Chlorinated phenols are priority pollutants, regulated by stringent discharge limits. The presence of chlorine increases the toxicity of these phenolic compounds and decreases their biodegradability. This study is to examine the removal of a priority chlorinated aromatic pollutant, 2,4,6-trichlorophenol (TCP), in aqueous solution by using Fenton's Reagent (a mixture of hydrogen peroxide and fenous iron catalyst), in terms of dechlorination and toxicity reduction. Test results indicate that the higher the molar ratio of H₂O₂ to TCP, the faster the release of chloride from TCP. However, the chloride released in all runs eventually approach the same level of theoretical chloride concentration, …
