METHOD FOR TREATMENT OF AQUEOUS EFFLUENTS CONTAINING METALLIC CATIONS

摘要

Aqueous effluents having a metallic ion charge, and especially those containing nickel, are stripped by subjecting said metallic ions to a treatment using complexing polymers, their metallic ion content then being sufficiently low for them to be safely discharged into the environment. The complexing polymers are regenerated by said treatment and can be reused after being optionally neutralized. The regenerating solutions are recyclable in treatment baths.
