| Abstract: | The kinetics of extraction of phenol from aqueous solution with emulsion-type liquid membrane containing bibutanediimide (surfactant) -kerosene as membrane phase and aqueous solution of sodium hydroxide as inner-aqueous phase has been investigated. The effect of components of outer-aqueous phase, inner-aqueous phase and membrane phase, stirring speed and temperature on the extraction rate were examined. The regularity of the extraction rate of phenol has been obtained. In experimental conditions the extraction rate of phenol may be controlled by diffusion process and the diffusion resistance exists mainly in the outer-aqueous phase. The diffusion step of phenol from outer-aqueous phase to the interface between outer-aqueous phase and membrane phase might be controlling step. |
