Selective Separation of Radiocesium from Complex Aqueous Matrices Using Dual Solid-Phase Extraction Systems

Origin of the exceptional selectivity of NaA zeolite for the radioactive isotope 90Sr2+

“…Several methods have been developed to remove 90 Sr 2+ , including adsorption, 5,[10][11][12] solvent extraction, 13,14 chemical precipitation, 15,16 membrane filtration, 5,17,18 and bio-treatment. 19 Because the concentration of 90 Sr 2+ is extremely low in nuclear wastewater, either adsorption via ion exchange or extraction with a strong binding site to 90 Sr 2+ is the most efficient and energy-saving method.…”
