Abstract
An immobilized receptor selectively sequesters Li+ and PF6− from aprotic solutions. Subsequent suspension in methanol serves to trigger the release of LiPF6. The recovered LiPF6 has ≥99.5% purity and no appreciable trace metal content as determined by qNMR spectroscopy and ICP-MS analysis.
