Abstract: Proposed are a method of preparing a cesium adsorbent and a cesium adsorbent prepared thereby. The method includes (a) preparing a powder mixture of coal mine drainage sludge (CMDS) powder, sodium hydroxide (NaOH) powder, and sulfur (S) powder and (b) heat-treating the powder mixture to prepare a cesium adsorbent. The cesium adsorbent increases the active ion exchange of Na and Cs and the bonding of S—Cs when adsorbing cesium ions, resulting in an average of 5 times higher Cs removal efficiency and adsorption capacity under various conditions compared to CMDS since CMDS relies on cesium adsorption by simple physical and electrostatic attraction. Moreover, the cesium adsorbent is eco-friendly and has excellent economic efficiency by utilizing waste CMDS.
