| Popis: | Uptake characteristics of a bis-amidoximated polymer are presented for 90Sr2+, 137Cs+, and 233UO22+ to assess rational ligand design and polymer engineering efforts applied to selective uranium extraction. Functionalized with the bis-amidoxime diaryl ether ligand at a loading of 1.98 mmol per gram of polymer, the polymer was found to sorb uranium from a pH 6 solution with a separation factor (α) over cesium of 1.2 × 103. Strontium uptake was negligible throughout the pH range studied whereas cesium uptake averaged |
