DEGRADATION OF TRICHLOROETHYLENE USING ADVANCED …

This research investigates degradation ,of trichloroethylene, (TCE) using a new treatment method called advanced reduction processes (ARPs). This new set of water treatment processes employ a source of activation energy to activate reducing agents and produce reducing radicals that can effectively degrade oxidized contaminants. Screening

Production. Prior to the early 1970s, most ,trichloroethylene, was produced in a two-step process from acetylene.First, acetylene was treated with chlorine using a ferric chloride catalyst at 90 °C to produce 1,1,2,2-tetrachloroethane according to the chemical equation. HC≡CH + 2 Cl 2 → Cl 2 CHCHCl 2. The 1,1,2,2-tetrachloroethane is then dehydrochlorinated to give ,trichloroethylene,.
