Reaction orders of radiation-induced dechlorinations of some aliphatic chlorinated hydrocarbons in aqueous solutions

Abstract Previously obtained data regarding radiation-induced dechlorination of some aliphatic chlorinated hydrocarbons tetrachloroethene (PCE), trichloroethene (TCE), chloroform (CHCl 3 ) and tetrachloromethane (CCl 4 ) in aqueous solutions were used for determination of formal reaction order of dechlorination. The influence of various factors on this process was investigated. It was found that the formal reaction order changes in the course of reaction and may depend on the initial concentration of chlorinated hydrocarbons.
