The extraction of Zr⁹⁵ and Nb⁹⁵ with an acetylacetone- chloroform mixture was investigated. The percentage extraction of Zr⁹⁵ with a 20% acetylacetone solution was 98% at pH values ranging from 3 to 8, and that of Nb⁹⁵ was 90% at pH values from 2 to 5. The extraction ratio of Nb⁹⁵ was lowered by the extension of the shaking time. As a diluent, chloroform and methylene chloride were recommended. Phosphate, oxalic acid, citric acid, and EDTA interfered remarkably. Sulfuric acid was most efficient for the back extraction. A high purity grade of Zr⁹⁵ was obtained by using hydrogen peroxide as a masking agent. The yield was satisfactorily high. (auth)
