In addition to removing organic contaminants, biochars have also been shown to remove metal contaminants and nutrients from wastewater and soil. Cao et al. (2009) investigated the sorption capacities of biochars produced by the pyrolysis of dairy manures at low temperatures (200oC and 350oC). They found that the biochar was six times more effective in removing lead (Pb) from wastewater than a commercial activated carbon. Broiler litter manure biochar enhanced the immobilization of heavy metals including cadmium (Cd), copper (Cu), nickel (Ni), and Pb in soil and water (Uchimiya et al. 2011). Yao et al. (2011) reported biochar derived from anaerobically digested sugar beet tailings (DSTC) removed 73% of phosphate from the tested water. Also, magnetic biochars were found to be effective at removing hydrophobic organic contaminants and phosphate from solution simultaneously (Chen, Chen, and Lv 2011). These results show the potential of biochars to minimize nutrient leaching in agricultural fields.
