Resumen:
In this paper the results of the transport of Cr(III) in a emulsion liquid membrane (ELM) are described containing as carrier di (2-ethyl-hexyl)phosphoric acid (D2EHPA)
The appropriate conditions for the chromium transport through the ELM were obtained from results of liquid-liquid extraction and stripping partition experiments.
The effect of both ionic concentrations of sulphuric acid and ammonium persulphate as strippant in the acceptor solution (internal phase); different constitutions from the liquid membrane (carrier concentration, amount of liquid paraffin like additive) and the influence different relations from aqueous internal phase/organic phase in the emulsion have been analyzed in the transport of chromium in the ELM.
