AB  - Hexabromocyclododecane (HBCD) is one of the priority persistent organic 
      pollutants (POPs), yet a cost-effective technology has been lacking for the 
      removal and degradation of HBCD. Zero-valent aluminum (ZVAl) is an excellent 
      electron donor. However, the inert and hydrophilic surface oxide layer impedes 
      the release of the electrons from the core metallic Al, resulting in poor 
      reactivity towards HBCD. In this research, a new type of modified mZVAl particles 
      (AC@mZVAl(bm/NaCl)) were prepared through ball milling mZVAl in the presence of 
      activated carbon (AC) and NaCl, and tested for adsorption and reductive 
      degradation of HBCD in water. AC@mZVAl(bm/NaCl) was characterized with a metallic 
      Al core with newly created reactive surface coated with a thin layer of crushed 
      carbon nanoparticles. AC@mZVAl(bm/NaCl) was able to rapidly (within 1 h) adsorb 
      HBCD (C(0) = 2 mg L(-1)) and thus effectively enriched HBCD on the carbon surface 
      of AC@mZVAl(bm/NaCl). The pre-enriched HBCD was subsequently degraded by the 
      electrons from the core Al, and  approximately 63.44% of the pre-sorbed HBCD was completely 
      debrominated after 62 h of the contact. A notable time lag ( approximately 12 h) from the onset 
      of the adsorption to the debromination was observed, signifying the importance of 
      the solid-phase mass transfer from the initially adsorbed AC particles to the 
      reactive Al-AC interface. Overall, AC@mZVAl(bm/NaCl) synergizes the adsorptive 
      properties of AC and the high reactivity of metallic Al, and enables a novel 
      two-step adsorption and reductive degradation process for treating HBCD or likely 
      other POPs.
