| Abstract: | Neutral crown ethers do not transport trivalent lanthanide cations in a H2O-CHCl3-H2O liquid membrane system. With the addition of a carboxylate group to a macrocyclic polyether, as in the case of sym-dibenzo-16-crown-5-oxyacetic acid, high efficiencies of transporting trivalent lanthanides were observed across the H2O-CHCl3-H2O liquid membrane. The crown ether carboxylic acid also showed significant selectivity for the lanthanides studied in this system. |
