Abstract

Co2[Fe(CN)6]/Fe3O4 nanoparticle adsorbent for ion cesium (Cs+) sorption was prepared by a chemical co-precipitation method. The magnetization of the materials makes them to be separated easyly from an aqueous solution by an external magnetic field. The ion Cs+ absorption by Co2[Fe(CN)6]/Fe3O4 nanoparticle follow the ion exchange mechanism, ion exchange capacity depends on the pH, the maximum ion exchange capacity of the material at pH = 4 is 0.40 meq (Cs+)/ g. After 15 min, about 98% of initial ion Cs+ concentration was removed from the solution, the adsorption could be described by Langmuir and Freundlich isotherms. The high adsorption capacity and good performance on other aspects, make the Co2[Fe(CN)6]/Fe3O4 nanoparticle a promissing adsorbent for the removal of ion Cs+ from water.
