Abstract |
Nano-assisted inclusion separation of alkali metals from basic solutions was reported by inclusionfacilitated
emulsion liquid membrane process. The novelty of this study is application of nano-baskets of
calixcrown in the selective and efficient separation of alkali metals as both the carrier and the surfactant.
For this aim, four derivatives of diacid calix[4]-1,3-crowns-4,5 were synthesized, and their inclusionextraction
parameters were optimized including the calixcrown scaffold (4, 4 wt%) as the carrier/
demulsifier, the commercial kerosene as diluent in membrane, sulphonic acid (0.2 M) and ammonium
carbonate (0.4 M) as the strip and the feed phases, the phase and the treat ratios of 0.8 and 0.3, mixing
speed (300 rpm), and initial solute concentration (100 mg/L). The results reveled that under the optimized
operating condition, the degree of inclusion-extraction of alkali metals was as high as 98-99%.
