Abstract: Cesium, with long half-life and huge harms to ecosystem, is one of the main components of radioactive waste water. Prussian blue analogue compounds have excellent cesium selective removal. However, Prussian blue direct application in cesium removal is not feasible due to difficulty with the solid-liquid separation that is caused by the fine particle size. In order to solve these problems, many studies have tried to load Prussian blue analogue on the different carriers. This approach increases the adsorption capacity of cesium, improves the removal of cesium and makes it possible to utilize without typical difficulty associated with separation of nanoparticles from solution. In this paper, the species of Prussian blue analogue composites and the reaction mechanism in terms of crystallography, reaction kinetics, adsorption isotherms and thermodynamic are introduced in detail. We hope to provide references for related research.
