Abstract

유전상수가 다른 여러 유기용매에 음이온교환체인 Aliquat336을 용해하여 다공성 고체 지지막에 함침시켜 액막을 제조하였다. 이 액막을 이용하여 아미노산과 첨가전해질이 역방향이동시 각 용매에서 첨가전해질의 종류와 농도변화에 따른 막전위와 아미노산의 이동속도와의 관계를 조사하였다.
실험결과 함침유기액막에서 막전위는 유기용매의 유전상수가 작을수록 작아져서 아미노산의 flux는 반대로 증가하였다. 첨가전해질이온의 선택투과계수 서열이 클수록 막전위가 작아져서 아미노산의 flux가 증가하였고 한계측정농도 이상에서는 첨가전해질의 농도가 커짐에 따라 막전위가 증가하여 아미노산의 flux는 감소하였다.

The relationship between membrane potential and flux of amino acid has been analyzed for the counter-transport system of amino acid coupled to the various concentration of added electrolytes through the sup-ported liquid membrane. The liquid membrane contained Aliquat 336 as liquid anion exchanger in various solvents with different dielectric constants. For the supported organic liquid membrane, solvents with lower dielectric constants was favored so that flux of amino acid was increased against it. The membrane potential decreased with increasing potentiometric selectivity se-quence of added electrolytes; however, the flux of amino acid increased. Above the detection limit the membrane potential increased with increasing concentration of added electrolytes; however, the flux of amino acid decreased.
