Destruction of Halogenated Aliphatics by Ultraviolet Catalyzed Oxidation with Hydrogen Peroxide

摘要: ABSTRACT Hazardous compounds are often present in water at low concentration levels, which can make their removal difficult and costly by conventional treatment processes. This project investigated the destruction of hazardous ultraviolet catalyzed oxidation using hydrogen peroxide as oxidizing agent. The effectiveness this process was determined for typical halogenated aliphatics, including trichloroethylene, tetrachloroethylene, tetrachloroethane, dichloromethane, chloroform, carbon tetrachloride ethylene dibromide. reactions were conducted a batch reactor equipped with pressure lamp. rates decomposition increased increasing temperature, highly dependent on chemical structure. With example, reduced from 50 ppm to less than 1 min 20°C 10 min. 40°C. All reacted chlorine converted chloride ion, indicating that th...
