    摘要: A process for recovering a substantial portion of nitric acid and metal ions from an acidic waste liquid produced in the process for the production of adipic acid by oxidizing cyclohexanone or cyclohexanol in a liquid phase, which comprises supplying said waste liquid to an electrodialysis apparatus including one or more electrodializers to recover said nitric acid and metal ions in a recovering liquid of a member selected from water and a diluted aqueous nitric acid.
