; ; ; ;
Competitive solvent extraction of alkaline-earth cations from aqueous solutions into chloroform by two series of lipophilic acyclic polyether dicarboxylic acids and one series of lipophilic acyclic polyether phosphonic acid monoethyl esters is reported. The influence of the polyether chain length and type of ionizable group upon extraction selectivity and efficiency is assessed.
