Abstract: The effectiveness of the chromatographic method of ion exchange for a periodic sepn. of radiochem. pure ⁹⁰Y from the parent isotope ⁹⁰Sr by the application of the ethylenediaminetetraacetic acid (I) as a chelating agent is described. The sepn. factor in 10^-2M solns. of I at pH 4.0-4.5 had a value 10³-10⁴. The conditions for the sepn. of Y from Sr were: column Dowex 50-X2 in the NH₄ form (200-230 mesh, column 30 cm. × 0.44 cm²), elution with 10^-2M I at pH 5.11.
