An anionic manganese(ii) metal–organic framework for uranyl adsorption†
Abstract
We report herein that an anionic metal–organic framework [Mn5(izdc)3(ox)3] can adsorb uranyl in water with high selectivity (Kd = 2041 mL g−1), large capacity (523 mg g−1) and fast dynamics (KS = 6.68 × 10−3 mg g−1 min−1). Grand canonical Monte Carlo simulation reveals that the coordination effect between the carboxylate O atoms and the equatorial position of the uranyl ion is the key behind this high-performance.
