Abstract

The composite of magnetic Fe(hydr) Oxide and cobalt potassium ferrocyanide with excellent adsorption capacity of cesium has been prepared by chemical coprecipitation method. The results of structural testing confirm the successful preparation of magnetic material K2[CoFe(CN)6]. It is applied as adsorbent for the separation of cesium from water solution. At pH 7 and 293 K, the maximum adsorption capacity for cesium can achieve to 141.44 mg/g. Adsorption of cesium on magnetic K2[CoFe(CN)6] surface is an spontaneous process. The as-synthesized adsorbent can be separated from aqueous solution in the magnetic field. The results of adsorption process show that it has the potential to be an effective adsorbent for practical use.
