Achieving highly efficient and selective cesium extraction using 1,3-di-octyloxycalix[4]arene-crown-6 in n-octanol based solvent system: experimental and DFT investigation

Abstract

Separation scheme was developed for selective extraction of long-lived fission product 137Cs using substituted calix crown 6 ether from aqueous acidic solution.

Structural investigation of the efficient capture of Cs+ and Sr2+ by a microporous Cd–Sn–Se ion exchanger constructed from mono-lacunary supertetrahedral clusters

“…The recovered 137 Cs and 90 Sr radionuclides can be further purified as excellent heating or radiation sources for nuclear batteries, thermoelectric generators and cancer radiotherapy, providing feasible ways for their recycling and comprehensive utilization. [13][14][15] Hitherto, Cs + and Sr 2+ pollutants have been eliminated through a variety of technologies, like precipitation, 16,17 solvent extraction, 18,19 membrane filtration, 20,21 biological treatment, 22,23 and ion exchange. 24,25 However, there are some specific disadvantages with these methods.…”
