Abstract

This article illustrates an experiment with the removal and recycling of Cr (VI) in a wastewater by the technique using an emulsion liquid membrane. The membrane solvent, the carriers and the types and amounts of stabiliser have been optimised. The liquid membrane recipe in optimal form is prepared as an emulsion to treat the water sample containing Cr (VI) so as to determine the effects of operating conditions, such as the pH of the internal and external water phase, the amount of carrier, the speed and the time of preparing the membrane, the membrane internal ratio and the emulsion water ratio.
