      carbide foams for odorous methyl mercaptan elimination: identification of 
      reactive oxygen species.

AB  - In this work, sludge-derived carbon (SC) was innovatively integrated with copper 
      oxide (CuO) on macroporous silicon carbide foams to construct a distinctive 
      catalyst (CuO/SC) with strong catalytic activity, which can effectively activate 
      persulfate (PS) for the removal of methyl mercaptan (CH(3)SH). The structure and 
      morphology of CuO/SC were investigated by means of XRD, SEM, and EDS. The effects 
      of initial pH values, copper contents, PS dosages, and flow rates on CH(3)SH 
      removal were also investigated. Under optimal condition, more than 90% of CH(3)SH 
      was removed by CuO/SC-PS combined system within 10-min reaction due to the 
      synergistic function of CuO and SC. More importantly, on the basis of reactive 
      species trapping and ESR spectroscopy, it is revealed that the responsible 
      reactive species for catalytic CH(3)SH composition were .SO(4)(-), .OH, (1)O(2), 
      and .O(2)(-) in CuO/SC-PS system. Finally, the possible PS activation scheme of 
      CuO/SC samples was proposed.
