Removal of nitrate and/or organic pollutants from effluents
摘要:
A continuous process for the removal of at least one of nitrate and organic contaminants from an aqueous effluent, which process comprises subjecting said effluent to extractive liquid ion-exchange with a long-chain alkylamine dissolved in an organic solvent and present in salt form, and reextracting the loaded organic phase with a base, the treated effluent being recycled for reuse.
