Magnetic Prussian blue (PB) nanocomposites were synthesized by binding PB to a core of magnetite (Fe3O4) nanoparticles for highly efficient and rapid separation cesium (Cs+) from aqueous solution. The average particle size the magnetic was 13.6 nm, they had high surface area (322.19 m2/g), leading Cs+ adsorption capability. showed maximum sorption capacity 280.82 mg/g at an initial concentration 50 mM, pH 7, 10 °C, which is much higher than those previously reported PB-based adsorbents removing Cs+. behavior followed pseudo-second-order kinetics obeyed Tempkin isotherm. on remained consistent even ionic competition in simulated seawater. obtained nanocomposite cost-effective adsorbent can be easily retrieved solution magnet after decontamination cesium. These results that has extensive applicability removal
