Determining Optimal Conditions for Electrochemical Conversion of Phase Flows Under Isotope Exchange

  • Published:
Russian Physics Journal Aims and scope

The paper considers the basic principles of organizing the isotope separation process for alkaline elements in a countercurrent of the two-phase ion-exchange system with electrochemical conversion of phase flows under the conditions of electromigration of isotopically substituted ion forms during electrodialysis. Mathematical models of the process of isotopic enrichment have been developed that take into account the electrochemical method of phase flow reversal with the flow moving in a column of an ion exchanger. The conditions for the transport of isotopic ions in vertical and horizontal directions have been established together with the time of diffusion of isotopically substituted ion forms through the working chamber of an electrodialysis apparatus operating under dynamic conditions of solution supply, energy consumption, and power supply. The results of theoretical research for two-phase exchange systems with subsequent electroregeneration of ion-exchange material are in good agreement with the available experimental data.
