Abstract: There is provided a method or a system for obtaining an aqueous solution substantially free of inorganic anionic pollutants selected from perchlorate, cyanide or chromate present therein, comprising contacting the aqueous solution containing said pollutants with a complex comprising micelles of an organic cation adsorbed on clay for removal of said pollutants from the aqueous solution. The method and system may also utilize a mixture of a complex of an organic cation adsorbed on clay as a micelle, and a granular material or a complex of an organic cation adsorbed on clay as a micelle. There is also provided a system comprised of a column accommodating the mixture of a complex of an organic cation adsorbed on clay as a micelle, and a granular material.
