Abstract

Among the many existing separation techniques, ion exchange on mineral ion exchangers seems to be the most promising one for the quantitative separation of long-lived fission products from acid reprocessing solutions.
Zirconium phosphate (ZrP) is suitable for the separation of Cs137 from reprocessing solutions desacidulated to 0.5 M HNO3. The specific activity amounts to 0.5 to 1 Ci/g ZrP when the feed solution contains 20 Ci/l.
Ferrocyanide molybdate (FeMo), a new mineral ion exchanger, allows the selective Cs137 separation from reprocessing solutions after their desac dulation to 2M HNO3 by formaldehyde (CH2O). The loading capacity for Cs137 amounts to 2 to 4 Ci/g FeMo.
