Functional groups present in the biosorbents that are responsible for metal binding are carboxyl, phosphoryl, sulfhydryl, amino, sulfate, imidazole, thioether, phenol, amide, and hydroxyl in various biomolecules of peptide, protein, and polysaccharide moieties of the cell walls.
The method is comprised of attaching a reactive group X--Y to a surface of a pigment; and subsequently displacing Y with an organic substrate N--S--ZM to form a surface-modified pigment having attached X--N--S--ZM; wherein X is a sulfonyl, phosphoryl, or 1,3,5-triazine group; Y is fluorine, chlorine, bromine or iodine; N is an amine, an imine, a pyridine, or a thiol group; S is substituted or unsubstituted alkyls, aryls, or polymer chains having a molecular weight range from approximately 300-8000; Z is a carboxyl, sulfonyl, phenolic, phosphoryl, ammonium, trimethylammonium, or tri-butylammonium group; and M is a halide, a negatively charged ion, a proton n salt form, or a cation in salt form.
