| Abstract: | Mechanochemistry, as a non-combustion technology, is featured by mild reaction conditions, simple operation, high efficiency, clean and wide application scope. In recent years, mechanochemical method has attracted considerable interests, especially for the destruction of chlorinated organic pollutants. Research on mechanochemical degradation of chlorinated organic pollutants was reviewed in detail. The development and characteristics of mechanochemical method were introduced. In addition, the types of single additives and combination additives commonly used in ball milling systems were summarized. The effects of ball milling device and operation parameters on the degradation of chlorinated organic pollutants were explored. Furthermore, the activation forms of additives and the mechanochemical degradation pathways of several typical chlorinated organic pollutants including hexachlorobenzene (HCB), polychlorinated biphenyls (PCBs), pentachlorophenol (PCP), dichlorodiphenyltrichloroethane (DDT), dechlorane plus (DPs) and polychlorinated naphthalenes (PCNs), were mainly elaborated. Finally, the problems to be solved were briefly described and future developments were prospected in view of the current research status on the degradation of chlorinated organic pollutants by mechanochemical method, whose purpose is to promote not only the in-depth study of mechanochemical theory but also the widespread application of mechanochemical technology. |
