| Abstract: | Halogenated hydrocarbon emulsion liquid membranes (e.g. trichlorobenzene) which were stabilized with polyamine tenside, using 18-crown-6 and picric acid as carriers, were applied to separation of strontium and calcium. Application in the separation of Sr/Ca enable us to enhance preconcentration factor for strontium due to decreasing occlusion of freed solution and better hydrodynamic parameters of the emulsion. |
