Abstract

A supported liquid membrane process was used for the selective transport of alkali earth cations from solutions containing a mixture of alkali and alkali earth chlorides. Bis‐trimethylpentylphosphinic acid (HDTMPP), an organophosphorous acid, was used as the carrier in the liquid membrane supported by a polypropylene fiber. It was found that the porous structure of polypropylene fiber suffered significant irreversible changes due to the formation of an inorganic salt of HDTMPP. This caused a reduction in the cation fluxes and the final failure of the supported liquid membrane.
