Abstract

Abstract

Carbon tetrachloride (CT) and tetrachloroethene (PCE) are the common contaminants in groundwater and drinking water because the chlorinated solvents are used in very large quantities and chlorine is used to disinfect drinking water. This paper describs the reductive dechlorination reaction using cheap iron scrapes. It discusses its kinetic process and factors that affect reaction rate. The results show that the zero valance iron is effective to the dechlorination of chlorinated hydrocarbon and that the reaction of CT is faster than that of PCE. Reaction is pseudo first order and the reaction rate is affected by specific surface area.
