Degradation of 1,2-dichloroethane from wash water of ion-exchange resin using Fenton's oxidation

摘要

Background, aim, and scope Chlorinated volatile organic compounds (CVOCs), widely used in industry as solvents and chemical intermediates in the production of synthetic resins, plastics, and pharmaceuticals, are highly toxic to the environment and public health. Various studies reported that Fenton's oxidation could degrade a variety of chlorinated VOCs in aqueous solutions. In acidic conditions, ferrous ion catalyzes the decomposition of H_2O_2 to form a powerful "OH radical. In this study, wastewater from wash of ion-exchange resin containing typical CVOC, 1,2-dichloroethane, was treated using Fenton's oxidation. To reduce environmental load and processing costs of waste-water, Fenton process as a simple and efficient treatment method was applied to degrade 1,2-dichloroethane of wash water.
