An experimental study on the removal of Cr(VI) through a supported liquid membrane (SLM) using a mixture Methyltrialkylammonium chloride (Aliquat 336), Tributyl phosphate (TBP) and kerosene as the liquid membrane (LM) was performed. Parameters affecting the extraction of Cr(VI) such as the Carrier/Solvent ratio in the liquid membrane phase and the Stirring rate of both feed and stripping phases were analyzed.Nevertheless, other factors such as the TBP/Aliquat ratio, solute concentration of feed, HCl concentration, stripping phase concentration and contact time were regarded in a constant level. Optimal experimental conditions for Cr(VI) removal (permeability of 2.565×10−5) were obtained after a 7 h separation with the Carrier/Solvent ratio of 0.5, the stirring rate of 500 min-1, the TBP/Aliquat 336 of 0.2, initial Cr(VI) concentration of 50mgL-1, HCl concentration of 0.05 mol L−1, NaOH concentration of 0.1 mol L−1.
