Current progress in remediation of chlorinated volatile organic compounds: A review

Chlorinated volatile organic compounds (Cl-VOCs) contamination has been recognized as one of the major problem in worldwide due to natural and anthropogenic activities. Recently, several treatment technologies (e.g., adsorption for broader concentration Cl-VOCs, catalytic combustion for high concentration (>500 ppm), advanced oxidation, electrochemical method, metal method and photo catalytic method for low concentration (<500 ppm)) have been applied for Cl-VOCs elimination. In this review, an extensive list of every method from literatures is compiled, and their capacities under various conditions are presented. However, there is still need to find out the practical technologies on commercial scale, leading to improvement of environmental pollution control.
