摘要：

The macrocycle-mediated fluxes of the alkali and alkaline earth metal cations have been determined in a H2O-CH2Cl2-H2O bulk liquid membrane system. It is found that transport of the alkali cations only occurred when the source phase pH was greater than the aqueous pKa value for the carriers. Transport increased regularly with increasing source phase pH. Transport alkaline earth cations from neutral pH source phases was minimal.
