  • A bulk liquid membrane system was introduced for selective separation of an amino acid mixture. We confirmed p-diamethylaminobenzaldehyde (DAB), sulfosalicylic acid (SSA) and 1-naphtol were very useful carriers for selective separation of an amino acid mixture. As a result, Ala, Leu, Val, Phe and Ile were successfully separated by SSA, 1-naphtol in basic condition, 1-naphtol in weak acidic condition, DAB in strong acidic condition and DAB in strong basic condition. The separation mechanism was proposed by ion pair mechanism in the case of SSA and 1-naphtol and Imine bond formation mechanism was also introduced for DAB.
