Enantioseparation by capillary electrophoresis (CE) in pure organic solvents (FA) was first reported by Sahota and Khaledi.Comparing with aqueous CE, researchers found that nonaqueous CE (NACE) has more advantages.The study on the chiral separation of binaphthol by CE, especially by NACE is limited.In this paper, para-sulfonyl-calix[6]arene was used as chiral selector.The NACE conditions were optimized.Using CH3CN-H2O(60∶40,v/v) as solvent, 25 mmol/L NH4Ac (pH=8.75) as the running background electrolyte, 10mmol/L para-sulfonyl-calix[6]arene as the additive, 30 kV as the applied voltage, R-and S-binaphthol enantiomers could be separated.
