    摘要: A method for removing a metal from a metal-containing solution comprising contacting the metal-containing solution with a metal-removing composition comprising a substrate, an organic ion, and a metal binding agent, and recovering a solution having a lowered metal concentration when compared to the metal-containing solution. A composition comprising a substrate, an organic ion, and a metal binding agent, wherein the substrate comprises a natural clay, a synthetic clay, a natural zeolite, a synthetic zeolite, a polymer resin, lignite, kaolinite, serpentine, illite, chlorite, smectite, montmorillonite, saponite, sepiolite, nontronite, beidellite, hectorite, fuller's earth, attapulgite, bentonite, analcime, chabazite, heulandite, natrolite, phillipsite, stilbite, diethyl aminoethyl, quaternary aminoethyl, or combinations thereof, wherein the organic ion comprises quaternary amines, imidazolium salts, phosphonium salts, tetra alkyl ammonium, bis-(hydrogenated tallow)-dimethyl-ammonium chloride, bis-(hydrogenated tallow)-benzyl-methyl-ammonium chloride, 4,5-dihydro-1-methyl-2-nortallow-alkyl-1-(2-tallow-amidoethyl)-imidazolium methyl sulfate, 1-ethyl-4,5-dihydro-3 -(2-hydroxyethyl)-2-(8-heptadecenyl)-imidazolium ethyl sulfate, or combinations thereof, and wherein the metal-binding agent comprises mercaptan, carboxylic acid, chelating agents, amines, esters, carboxylic acids, alcohols, ethers, aldehydes, ketones, alkenes, alkynes, mercaptans, thiols, tert-dodecanethiol, nonanethiol, octanethiol, n-stearic acid, iso-stearic acid, palmitic acid, or combinations thereof.
