ANALYTICAL STUDY OF TYPE-1 FACILITATED TRANSPORT THROUGH LIQUID SURFACTANT MEMBRANE

In the present study, a mass transfer model for Type-1 facilitated tra nsport in liquid surfactant membrane is developed by taking into consi deration a size distribution of emulsion drops, and analytical solutio n of the model equations has been presented. The model takes into acco unt the continuous phase and outer liquid membrane phase resistances a long with diffusion through composite emulsion drop. Effort has been m ade to highlight the effect of the various system parameters on the ex traction rate including computation of reaction front position. The re sults of this work are found to be in good agreement with the publishe d experimental results on batch extraction of phenol using NaOH as int ernal reagent. The model would thus provide an insight of the separati on mechanism involved in the mass transfer processes in this type of s ystem.
