A comparison of models for 2-chlorophenol recovery from aqueous solutions by emulsion liquid membranes

Abstract

Advancing front model and three reversible reaction models were applied to describe 2-chlorophenol permeation from aqueous solutions by emulsion liquid membranes. Similar results were obtained in most cases by using either of the reversible reaction models. Also differences between reversible reaction and the advancing front model were shown to be within experimental error in most cases (with the exception of low temperature permeation data) meaning that the role of reversibility of the chemical reaction between internal phase reagent and 2-chlorophenol can be considered negligible. Both advancing front and reversible reaction models can be used with a reasonably accuracy as estimates of 2-chlorophenol permeation for design purposes.
