In a study of mechanochemical (MC) dechlorination treatment, hexachlorobenzene (HCB) was chosen as a model pollutant with aluminum and alumina (Al+Al2O3) powders as the co-milling regents. Both intermediate analysis and quantum chemical calculations were adopted to elucidate the free radical dechlorination mechanism of HCB. The researchers found that the intermediates and radical-related reactions in the mechanochemical dechlorination of HCB were quite different from what happens in a typical photocatalytic dechlorination process. Impacts of different radical reactions on HCB dechlorination were also compared.
