Magnetic prussian blue/graphene oxide nanocomposites caged in calcium alginate microbeads for elimination of cesium ions from water and soil.

Highlights: [•] Magnetic prussian blue/graphene oxide–calcium alginate microbeads were prepared. [•] Microbeads could be separated rapidly by an external magnetic field. [•] Adsorption properties for Cs+ of microbeads were studied. [•] The microbeads present high efficiency and good selectivity to Cs+. [•] The microbeads are convenient for treatment of cesium-contaminated water and soil. [ABSTRACT FROM AUTHOR]
