Facile Synthesis of Nanolayered Manganese Oxide for the Efficient and Selective Removal of Strontium(II) from Nuclear Wastewater.

ABSTRACT: Efficient and selective removal of radioactive ⁹⁰Strontium (⁹⁰Sr) from nuclear wastewater is a sustainable strategy for nuclear energy development and environmental protection due to its long half-life and high biochemical toxicity. Herein, a novel nanolayered manganese oxide material (Na_0.7MnO_2.05, Na-NLMO) is proposed and its application for Sr(II) capture in both simulated waste liquid and real natural water systems. Na-NLMO is tailored for Sr(II) adsorption through a simple and rapid solid-phase reaction, which has good chemical stability and a strong affinity for Sr(II) across the pH range of 1 to 8. The maximum adsorption capacity is 145.21 mg g^-1 taking advantage of the solid-liquid ratio of 0.67 g L^-1. The loaded Sr(
