•Immobilization of metals by BC-nZVI process was superior to that of BC or nZVI.•Immobilization of Cd or Pb was inhibited with addition of 2,4-dichlorophenol.•Cd and Pb availability decreased, whereas soil pH and organic matter increased.•Stable metals speices such as CdCO3, Cd(OH)2, PbCO3 and Pb(OH...
