Selective cesium removal from radioactive liquid waste by crown ether immobilized new class conjugate adsorbent

- DB24C8 crown ether was functionalized for preparation of conjugate adsorbent.
- Radioactive 137Cs can be selectively removed by the conjugate adsorbent.
- Adsorbent can effectively capture Cs even in the presence of a high amount Na & K.
- Adsorbent is reversible and able to be reused without significant deterioration.
