Alkall-metal catlon sorptlon from aqueous and aqueous methanok solutions and column concentratlon of alkalhnetal catkns from dlkrte squeow sdutkns by carboxylic add resins contalnlng dlbenzo-14crown-4 units and thelr acycllc polyether analogues have been Investlgated. The crown ether carboxyllc acld reslns exhlbit enhanced sorption selectlvlty over the acycllc polyether resins. Good sorptlon selectlvlty for Ll'and Na'was obtalned wlth ...
