Abstract
(Allyloxy)methyl-Crown Ether를 액체막계에서 금속이온의 운반체로 사용하였다. 운반체로 사용한 AMDT18C6는 경쟁이동반응에서 Pd(II)를 선택적으로 분리하였으며 AM18C6는 Pb(II)의 선택성이 있었다. 거대고리리간드와 금속이온과의 착물형성에 관한 연구는 전위차법과 용액열량계법을 이용하였다.

(Ally1oxy)methyl-Crowvn Ethers have been used as metal cation carriers in a bulk liquid membrane system Competitive transports by the AMDT18C6 and the AM18C6 are selective for Pd(II) ion and Pb(II) ion over other transition metal cations respectively. Studies of complexations of (Allyloxy)methyl-Crown Ethers with metal cations have been carried out by titration calorimetry and potentiometry.
