TI  - Separation of amino-acid enantiomers using micellar-enhanced ultrafiltration.
PG  - 690-8
AB  - Micellar-enhanced ultrafiltration (MEUF) is investigated as a large-scale 
      technique for separating amino acid enantiomers. Specifically, L-5-cholesterol 
      glutamate, a chiral ligand-exchange cosurfactant, is used together with a 
      nonionic surfactant to form mixed micelles that preferentially bind 
      D-phenylalanine over L-phenylalanine in the presence of copper(II). Operational 
      selectivities as high as 4.2 are obtained. Potentiometric titrations using a 
      water-soluble model compound similar to the chiral cosurfactant indicate that the 
      ternary copper complex with phenylalanine has a stereoselectivity for the D 
      enantiomer which is significantly smaller than that observed in the MEUF system. 
      Thus, the selectivity of the chiral legend's local solvent and structural 
      environment.
