Abstract
Fenton's Reagent is a strong oxidant for 2,4,6 Trichlorophenol (TCP) in aqueous phase. This reaction can be effectively utilized to treat an industrial wastewater containing TCP, and reduce the toxicity of the discharge. This paper reports the effects of the amounts of the oxidant (hydrogen peroxide) and the catalyst (ferrous ions), relative to TCP, on the rates and extents of reaction. The progress of each reaction has been monitored in terms of TCP removal, chloride ions release from the organic structure, change in pH, and the reductions in COD and TOC. This information is important in order to maximize the level of treatment with minimum application of chemicals. A set of optimum molar ratios of oxidant to substrate, and catalyst to oxidant were determined.
