摘要

Sulfonated styrene–divinylbenzene (SS-DVB) resins with controlled crosslinking densities (10% and 20%) were developed for the removal of 137Cs, 110mAg, and 60Co from low-level liquid radioactive waste. Maximum removal efficiencies of 73± 2%, 84 ± 3%, and 75 ± 3% were achieved at pH 4. Sorption equilibrium was reached within 60 min, with maximum capacities of 153.8 Bq g−1 (137Cs), 92.4 Bq g−1 (110mAg), and 11.3 Bq g−1 (60Co). The results demonstrate effective radionuclide removal under multi-component conditions, highlighting the potential of SS-DVB resins for radioactive wastewater treatment.
