Competitive liquid-liquid extraction of alkali metal cations from water into organic solvents containing the ionizable crown ether 2-((sym-dibenzo-16-crown-5)oxy)decanoic acid is reported. Extraction efficiency decreases as the organic solvent is varied in the order chloroform > 1,1,1-trichloroethane > tetrahydronaphthalene > benzene > toluene > p-xylene. Extraction selectivity for Na/sup +/ is much higher in chloroform than in the other organic solvents. The relationship between empirical solvent polarity parameters and the selectivity and efficiency of extraction is explored.
