Abstract	Dibenzo-18-crown-6(DBC) 및 dicyclohexyl-18-crown-6(DCC)를 이온의 운반체로 하는 여러 유기액체막을 통해 수소이온의 운반속도를 25℃에서 측정하였다. 운반속도는 용매의 유전상수에 크게 영향을 받는데 이를 액체막 내부에서 이온 화학종이 가진 Born의 포텐셜 에너지 장벽을 들어 고찰하였다. 또한 음이온의 크기도 운반속도에 영향을 주었는데 이는 Born식으로 부터 새로이 유도된 이론적인 결과와 잘 일치하였다. The transport rates of H+ ion by DBC and DCC as carrier molecules through organic liquid membranes were determined at 25℃. The transport rates depend highly on the dielectric constants of membrane solvents and these results were discussed in terms of Born's potential energy barrier methods. The sizes of anions also affect the transport rates and these results were well explained theoretically by extended Born's equation.
