Removal of Cesium in Water Using Novel Composites Synthesized Nano-Sized Prussian Blue with Carbonyl Iron.

Among the various radioactive materials, Cesium is a major source of radioactive contamination and known to be the most dangerous radioactive material, can cause enormous damage to the ecosystem environment when released into the environment. Prussian Blue (PB) has been used as an adsorbent to effectively remove cesium, however it has the problem of being difficult to separate in water. In this study, carbonyl iron (CI) which is known as ferromagnetic synthesized with precursor of PB (FeCl₃ and potassium ferricyanide) to solve the problem of PB particles.
