Enhancing radiostrontium uptake by a layered titanate perovskite via sustainable electrochemically switched ion exchange.

ABSTRACT: Green and sustainable ⁹⁰Sr uptake is urgently needed for radionuclides remediation. Herein, we propose an efficient strategy based on electrochemically switched ion exchange (ESIX) method to enhance ⁹⁰Sr uptake using electroactive ion exchange material. A titanate perovskite (Na₂La₂Ti₃O₁₀) with outstanding acid, irradiation resistance, and thermal stability can effectively capture Sr²⁺ and achieve remediation of actual acidic ⁹⁰Sr-containing liquid waste (R^Sr > 99%). Na₂La₂Ti₃O₁₀ is prepared as working electrode C@NaLaTiO to enhance Sr²⁺ uptake via ESIX. Remarkably, the Sr²⁺ adsorption capacity increases (from 104.84 to 175.43
