Amino acid resolution using supported liquid membranes

The results obtained here indicate that the experimentally determined separation factor and flux of each enantiomer initially decrease rapidly. The initial separation factor is the highest separation factor achieved during the run. The highest separation factors for phenylalanine and methionine were 1.8 and 1.9, respectively. The initial separation factor may be used to determine the ratio of the enantioselective equilibrium constants for the d and l stereoisomers. As the two enantiomers are resolved, the ratio of the d to l enantiomer in the feed suspension will deviate from one. The ratio of the enantioselective equilibrium constants may be used to estimate the maximum concentration difference possible between the d and l enantiomers in the feed solution.
