AB  - Risk associated with heavy metals in soil has been received widespread attention. 
      In this study, a porous biochar supported nanoscale zero-valent iron (BC-nZVI) 
      was applied to immobilize cadmium (Cd) and lead (Pb) in clayey soil. Experiment 
      results indicated that the immobilization of Cd or Pb by BC-nZVI process was 
      better than that of BC or nZVI process, and about 80% of heavy metals 
      immobilization was obtained in BC-nZVI process. Addition of BC-nZVI could 
      increase soil pH and organic matter (SOM). Cd or Pb immobilization was inhibited 
      with coexisting organic compound 2,4-dichlorophenol (2,4-DCP), but 2,4-DCP could 
      be removed in a simultaneous manner with Cd or Pb immobilization at low 
      concentration levels. Simultaneous immobilization of Cd and Pb was achieved in 
      BC-nZVI process, and both Cd and Pb availability significantly decreased. Stable 
      Cd species inculding Cd(OH)(2), CdCO(3) and CdO were formed, whereas stable Pb 
      species such as PbCO(3), PbO and Pb(OH)(2) were produced with BC-nZVI treatment. 
      Simultaneous immobilization mechanism of Cd and Pb in soil by BC-nZVI was thereby 
      proposed. This study well demonstrates that BC-nZVI has been emerged as a 
      potential technology for the remediation of multiple heavy metals in soil.
