Porous structured potassium ferric hexacyanoferrate-alginate/clay hydrogel for selective and rapid cesium adsorption |
| 초록 |
Radioactive contaminant adsorbents require well-designed morphologies for effective interaction with radioactive species selectively and high structural stability during adsorption. Herein, we demonstrate a pomegranate-like micro-scavenger cage (P-MSC) with high adsorption capacity towards radioactive cesium (137Cs). The resulting micro-scavenger cage shows enhancing properties compared to alginate bead gelled by traditional methods using Ca2+. The proton-exchange between cesium and P-MSC result in rapid adsorption, within 10 min, with a high removal capacity. The resulting P-MSC has a 236-fold higher distribution coefficient toward cesium than traditional Ca-alginate bead. The maximum cesium removal capacity of the P-MSC is 108.06 mg/g. It is found that the P-MSC have a removal efficiency of 99.24% for radioactive cesium, showing that the material holds great promise for the clean-up of radioactive cesium contaminated seawater around nuclear plants and/or after nuclear accidents. |
