| Abstract: | The role of biomass charcoal porous,surface activity,selective adsorption and high based properties in the effective control of heavy metal biological migration was given in order to provide reference for heavy metal contaminated soil remediation technology. The general situation of heavy metal contaminated soil in China was introduced and the application of biomass carbon in heavy metal contaminated soil remediation was reviewed. The effects of phytoremediation,chemical leaching,soil performance improvement,curing/stabilization,thermal desorption repair and electrokinetic repair were highlighted. The effects of raw material types,pyrolysis temperature and surface functional groups on biomass carbon and biomass carbon on soil environment were briefly introduced. The future of biomass charcoal application in heavy metal contaminated soil remediation was prospected. |
