•An efficient method for fabrication of Prussian blue functionalized magnetic nanocluser.•Fabricated magnetic absorbent exhibit excellent removal efficiency of radioactive 137Cs from water.•Fast and easy magnetic separation of Prussian blue functionalized absorbent from water.•The magnetic absorbent has promising application for the cleanup and treatment of 137Cs-contaminated water.
Prussian blue-functionalized magnetic nanoclusters were fabricated for the highly efficient removal of radioactive cesium (such as 137Cs) and rapid magnetic separation of absorbent from 137Cs-contaminated water. The magnetic nanoclusters, synthesized via the hydrothermal method, were coated with Prussian blue (PB) via a simple reaction with potassium hexacyanoferrate under acidic conditions. The resulting Prussian blue-functionalized magnetic nanoclusters had a large distribution coefficient, even in the presence of 3000 ppm competing ions such as K+, Na+, Ca2+ and Mg2+, and excellent removal efficiency (>99.7%) of radioactive cesium from contaminated water. Furthermore, they possess good saturation magnetization values (27.5 emu/g), allowing for rapid separation from an aqueous solution using an external magnetic field. Therefore, these magnetic adsorbents have promising applications for the treatment of radioactive cesium-contaminated water.
