Article Synopsis
  • Selective separation of cesium (Cs) is crucial for advancing nuclear energy sustainability and protecting the environment due to its radioactivity and long lifespan.
  • The current challenges in separating Cs from radioactive waste stem from strong interactions between adsorbents and high-valency ions, but a new strategy involving layered perovskites has been proposed.
  • HLaNbO, a niobate-based perovskite, exhibits exceptional selectivity for Cs over competing ions due to its specific structural features, as confirmed by molecular-level analyses and theoretical calculations, offering insights for developing effective materials for radionuclide remediation.

Cs and Sr are hazardous to ecological environment and human health due to their strong radioactivity, long half-life, and high mobility. However, effective adsorption and separation of Cs and Sr from acidic radioactive wastewater is challenging due to stability issues of material and the strong competition of protons. Herein, a K -activated niobium germanate (K-NGH-1) presents efficient Cs /Sr coadsorption and highly selective Cs /Sr separation, respectively, under different acidity conditions.
