Resumen
Emulsion liquid membranes have been successfully used for the removal of different
types of organic and inorganic pollutants by means of carrier-mediated transport mechanisms.
However, the models that describe the kinetics and transport of such mechanisms are very complex
due to the high number of model parameters. Starting from an analysis of the similarity between
the elemental mechanisms of carrier-mediated transport in liquid membranes and of transport in
adsorption processes, this paper presents an experimental analysis of the possibility of applying
kinetic and mechanistic models developed for adsorption to carrier-mediated transport in emulsion
liquid membranes. We study the removal of a target species, in this case, Cu(II), by emulsion
liquid membranes containing membrane phase solutions of benzoylacetone (carrier agent), Span 80
(emulsifying agent) and kerosene (diluent), and hydrochloric acid as a stripping agent in the product
phase. The experimental results fit the ...
