Abstract

Alkall-metal cation sorption from aqueous and aqueous methanolc solutions and column concentration of alkall-metal cations from dilute aqueous solutions by carboxylic add resins containing dibenzo-14-crown-4 units and their acyclic polyether analogues have been Investigated. The crown ether carboxylic acid resins exhibit enhanced sorption selectivity over the acyclic polyether resins. Good sorption selectivity for Ll⁺and Na⁺was obtained with a cyclic polyether resin In which the carboxylic acid group Is positioned over the crown ether ring. For column concentration of alkall-metal cations from dilute aqueous solutions, gradient elution of the sorbed metal Ions from the resin with the carboxylic acid group positioned over the crown ether cavity gave selective column concentration of Ll⁺and Na⁺.
