Abstract
|
|
|
|
(Allyloxy)methyl-Crown 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.
