Selective separation of radionuclides from aqueous matrices using crown Ether: A review

Concerns about hazardous long-lived radionuclides (RNs) in the environment have fueled interest in selectively separating RNs, particularly in the aftermath of the Chornobyl and Fukushima disasters. The current review focuses on the use of crown ethers (CEs) to separate long-lived radioisotopes, such as cesium, strontium, and technetium, from aqueous matrices. The review guides the selection of appropriate CEs for developing efficient absorbents, providing valuable insights for separating and analyzing RNs in environmental matrices.
