We demonstrate that a tripodal hexaurea receptor can selectively bind PO43− anions via 12 hydrogen bonds with up to 3.8 × 106 M−1 binding affinity in DMSO, which is 38-fold stronger than SO42−. This receptor facilitates the extraction of PO43− from strongly basic aqueous solutions into chloroform using liquid–liquid extraction, followed by its release as the H2PO4− anion into an acidic solution. This pH-dependent phosphate extraction successfully enables selective separation of phosphate and sulfate anions. [ABSTRACT FROM AUTHOR] |
