Separation of Bromine by Liquid Surfactant Membranes

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 218)

Abstract

The method of separating bromine using emulsion liquid membrane is described. The effects of various experimental parameters, such as the concentration of surfactant and internal phase reagent, the proportion of oil and internal phase reagent, and the proportion of emulsion and water have been studied in detail. With Blue 113-B as surfactant, kerosene as the membrane solvent, Na2CO3 as the internal phase reagent, N7301 as carrier, bromine is extracted by emulsion liquid membrane system. The migration mechanism is discussed; the best operating conditions for the separation: the surface-active agent dosage Blue 113-B is 2–3 %, N7301 dosage as carrier is 2 %, the appropriate proportion of emulsion and water is 1:30, the appropriate proportion of oil and internal phase reagent is 5:5. In the best operating conditions, the extraction efficiency could achieve 98 %; after the breaking, bromine recovery can reach 95 %.
