AB  - Mechanochemical destruction (MCD) is a good alternative to traditional 
      incineration for the destruction of persistent organic pollutants (POPs), like 
      hexachlorobenzene (HCB), and the key is to find an efficient co-milling reagent. 
      Toward this aim, HCB was milled with various reagents in a planetary ball mill at 
      room temperature, and CaC(2) was found to be the best one. HCB can be destroyed 
      completely within 20 min at a mass ratio of CaC(2)/HCB = 0.9 and a rotation speed 
      of 300 rpm. The ground samples were characterized by X-ray diffraction, X-ray 
      photoelectron spectroscopy and Fourier transform infrared spectroscopy. The 
      results show that the destruction products are nonhazardous CaCl(2) and carbon 
      material with both crystalline and amorphous structures. On these bases, possible 
      reaction pathways were proposed. Considering its excellent efficiency and safety, 
      CaC(2) may be the most feasible co-milling regent for MCD treatment of HCB. 
      Further, the results are instructive for the destruction of other POPs.
