Research of the physical properties of the liquid radioactive waste treatment ion-selective sorbents

Abstract

The prospects of ion-selective treatment for the liquid radioactive waste volume reducing are shown. The main problems of the hydrodynamics scale-up and ion-exchange equipment design are outlined. The short review of the methods of packed bed hydrodynamic processes modeling is presented. The experimental research technique of the required physical properties of the EKOSORB ion-selective sorbents for the hydrodynamic design and scale-up of the liquid radioactive waste treatment ion-exchange equipment is shown. The results of the liquid radioactive waste treatment ion-selective sorbents true and bulk density and porosity measurements are shown. The micro photos and data on the ion-selective sorbents particle's form, size, and structure are presented. The ion-selective sorbents layer pressure drops were calculated by the Ergun's equation. © 2021 Author(s).
