摘要： This invention relates to a process for the purification of waste waters containing organic and, should the situation arise, inorganic sulphur compounds, which waste waters contain a proportion of mercaptobenzothiazole and/or derivatives thereof and, should the situation arise, a proportion of benzothiazole and/or derivatives thereof and/or mercaptobenzimidazole and/or derivatives thereof and, should the situation arise, thiosulphate, whereby the waste waters are treated with an extracting agent comprising salts of aliphatic amines and aliphatic and/or aromatic hydrocarbons.

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.
