AB  - Mechanochemical destruction (MCD) has been recognized as a promising 
      non-combustion technology for the disposal of obsolete pesticides belonging to 
      the persistent organic pollutants (POPs). Mirex, a termiticide ever used for many 
      years in China, was ball milled in the presence of various reagent(s) in a 
      planetary ball mill at room temperature to investigate the destruction 
      efficiency. The ground samples were characterized and analyzed by Fourier 
      transform infrared spectroscopy (FTIR), Raman spectroscopy, gas chromatography 
      (GC), and ion chromatography (Martins, Bicego et al.). Under the same conditions 
      of mill rotary rate and charge ratio, the mixture of iron powder and quartz sand 
      (Fe/SiO(2)) was found best in promoting the mirex destruction. Mirex was 
      completed destroyed after 2 h grinding at a charge ratio of 36:1 (reagent/mirex, 
      m/m) and a mill rotation speed of 550 rpm. No organic compound was detected by 
      GC/muECD screening. The yield of water-soluble chlorine determined by ion 
      chromatography (Martins, Bicego et al.) in the final residue accounted for 90.7% 
      of chlorine in the original mirex, which indicated a nearly complete 
      dechlorination. Signals of both graphite and amorphous carbon were found in the 
      Raman spectra of the co-ground powder samples. With the main final degradation 
      products of water soluble Cl and carbon, the mechanism of the mechanochemical 
      destruction approach should be dechlorination followed by the carbonization.
