Ion-Exchange Processes in Deactivated Liquid Radioactive Waste
https://doi.org/10.18412/1816-0395-2018-1-20-25
Abstract
Effective technological solutions for in-depth comprehensive deactivation of high-salt liquid radioactive waste, containing organic complexing agents (ethanedioic, vinegar, citric and other acids), from 134,137Cs, 90Sr, 60Co radionuclides and rare-earth elements, based on ion-exchange techniques, have been developed. Extracting of radionuclides unbound with organic ligands from solutions is effective with ion-exchange materials based on oxotitanium(IV) hydrophosphates possessing high sorption characteristics and providing a reliable radionuclide immobilization. Radionuclides, forming strong complex organic compounds, are extracted using the ion-exchange techniques from the complex which is followed by sorption and co-precipitation.
