SORPTION SEPARATION OF NIOBIUM-ZIRCONIUM CATIONS MIXTURE

The work shows for the first time the possibility of using sorption technologies to separate a mixture of radioactive niobium and zirconium cations, which are part of the waste generated in the nuclear fuel cycle. The separation of these atoms will significantly reduce the costs of waste disposal, as well as provide an opportunity to reuse zirconium ions. In this work the process of ion separation using anion exchanger AB-17-8 is investigated in detail, conditions for more effective realization of the process under dynamic conditions are selected and its mechanism is proposed.
