摘要

Process for extracting metal contents from aqueous solutions, characterized in that it comprises treating the aqueous solution with a solution, in an organic solvent immiscible with water, of a ligand capable of forming a complex compound with the metal, and extracting the metal in the form of the complex compound from the aqueous phase with the water-immiscible organic solvent, such being the amount of ligand and organic solvent that the ligand becomes completely soluble in the organic solvent and the complex compound thus formed is not completely soluble in the organic solvent. The organic solvent phase but is completely associated with it. (Machine-translation by Google Translate, not legally binding)
