- Abstract
Cutting-edge research introduces a chemical reactor for liquid radioactive waste treatment, utilizing a four-stage radiochemical separation. Biomass conversion yielded activated carbons with impressive adsorption capacities up to 1 × 104 Bq/g and proved effective for Cs removal. Standout coagulants, AlCl3·6H2O and FeSO4·7H2O, achieved an 80% decontamination factor for six radionuclides. Sulphonated DVB ion-exchange resins showed high efficiency, achieving 100% Cs decontamination at pH 4 ± 2. Integrated processes successfully decontaminated twelve radionuclides up to 99 ± 1% with substantial demineralization of waste, up to 95%, was achieved. Current reactor system is invaluable for routine and emergency scenarios for treating liquid radioactive waste with varying radionuclide compositions.
