摘      要：Biochar(BC)has gained attention for removal of toxic elements(TEs)from aqueous media;however,pristine biochar often exhibits low adsorption ***,various modification strategies in BC have been developed to improve its removal capability against *** zero-valent iron(nZVI)and iron oxides(FeOx)have been used as sorbents for TE ***,these materials are prone to agglomeration and also expensive,which make their usage limited for large-scale *** nZVI technical demerits could be resolved by the development of BC-based composite sorbents through the loading of nZVI or FeOx onto BC *** zero-valent iron modified BC(nZVIBC),FeOx-modified BC(FeOxBC)have attracted attention for their capability in removing pollutants from the aqueous ***,a potential use of nZVIBC and FeOxBC for TE removal from aqueous environments has not been well-realized or *** such,this article reviews:(i)the preparation and characterization of nZVIBC and FeOxBC;(ii)the capacity of nZVIBC and FeOxBC for TE retention in line with their physicochemical properties,and(iii)TE removal mechanisms by nZVIBC and *** nZVI and FeOx in BC increases its sporptive capability of TEs due to surface modifications in morphology,functional groups,and elemental *** combined effects of BC and nZVI,FeOx or Fe salts on the sorption of TEs are complex because they are very specific to *** review identified significant opportunities for research and technol-ogy advancement of nZVIBC and FeOxBC as novel and effective sorbents for the remediation of TEs contaminated water.
