Abstract

Stripping reagents of molybdenum(IV) from an organic solution of molybdenum-alkylphosphonic acid monoester complex were examined. It was clarified that aqueous solutions of polyhydroxyalcohol and saccharide are effective as stripping reagents in the above system. Among them, quantitative stripping could be attained by using a mannitol aqueous solution in the pH range above 4. The dependence on the concentration of mannitol and extractant was investigated. It was found that nonionic species of molybdenum forms aqueous-soluble complex with mannitol. From the experimental results, the stripping reaction of molybdenum with mannitol (L) was deduced as follows ∗ [formula omitted].
