  • Surface-modified biomass, preparation method thereof, and method for recovering valuable metals using the same
    Patent number: 8906132
    Abstract: The present invention relates to a surface-modified biomass which is crosslinked with an amine group-containing cationic polymer on the surface of a cell biomass, its preparation method, and a method for recovering valuable metals using the same. The surface-modified biomass of the present invention has an advantage of improving adsorption of and affinity with anionic pollutants as a result of further introducing a cationic functional group by crosslinking of the amine group-containing cationic polymer on the surface of the biomass. In addition, the method for recovering valuable metals with the present invention is environment-friendly, economical, and harmless to the human body.
