Abstract

A novel solvent system containing a newly synthesized both-side diglycolamide-functionalized calix[4]arene (L-I) in a room temperature ionic liquid showed highly efficient extraction of actinides and a remarkable acid concentration independent extraction of trivalent actinide ion, Am3+ suggesting its possible use for high level radioactive waste remediation. The nature of the complexes was ascertained by slope analysis, luminescence spectroscopic investigations and from the thermodynamic parameters. The sustainability of the solvent system for long term applications was also investigated.
