摘要：

Extraction of amino acids from aqueous solutions into chloroform with di(2-ethyl-hexyl)phosphoric acid was studied. The extraction efficiency decreases in the sequence Tip > Phe > Leu > Arg > Lys > lie > Ata > Gly. The addition of dicyclohexyl-18-crown-6 improves the efficiency. and kinetics of extraction of most amino acids. The extraction degree depends on the concentration of the crown ether.
