LIQUID-MEMBRANE SEPARATION OF AQUEOUS MIXTURE

摘要

PURPOSE:To transfer efficiently dissolved substances to an internal water phase by using a polyglycerine condensate of recinoleic ester as an emulsifier of a w/o type emulsion. CONSTITUTION:When dissolved substances are removed from an aq. soln. by using a w/o type emulsion, a polyglycerine condensate of recinoleic ester is used as an emulsifier for forming the w/o type emulsion. When the w/o emulsion thus prepared is brought into contact with an aq. soln. contg. various kinds of dissolved substances, the dissolved substances can be efficiently transferred to the internal water phase.
