ABSTRACT:
A method for removing toxic anions from water is provided. A complexing agent, such as a cationic polyelectrolyte, is added to untreated water. The cationic polyelectrolyte complexes with anions, such as chromate, and the complex is filtered out of the water. The complex is then treated with barium chloride, lead chloride, aluminum, iron, or zinc to precipitate chromium ions and to regenerate the complexing agent. The regenerated complexing agent can be reused for water treatment.
