Previous studies demonstrated that black carbon (BC) in soils arising from the burning of crop residues is a highly effective adsorbent for organic contaminants. This work evaluated the adsorptive ability of BC for heavy metals in relation to the BC surface characteristics. Two BC samples, rice carb...
