Recovery of 2-chlorophenol from aqueous solutions by emulsion liquid membranes: batch experimental studies and modelling

A study of 2-chlorophenol recovery by emulsion liquid membranes was undergone. The effect of several permeation variables such as membrane phase composition, internal reagent concentration, solute concentration, permeation stirring speed, temperature, permeation time and phase ratios between membrane phase and internal phase and also between external phase and internal phase on 2-chlorophenol permeation was studied. The most relevant of these parameters were permeation stirring speed, temperature and phase ratio between external phase and internal phase. Advancing front model was applied to these parameters and described the experimental results.
