This work is intended for extraction and recovery of toxic heavy metal components, viz . Cadmium (Cd), from the industrial wastewater using liquid membrane (LM)‐based separation technique. Exploring environmental benignity in the solvent (LM) is the main aim of this work. Vegetable oils are potential candidates toward that. Presence of carrier component in solvent often augments the solute transport mechanism. Although N , N ‐dimethyloctylamine (DMOA) is a very good carrier to show excellent extraction, the recovery is poor possibly because of high stability of complex between Cd(II) and DMOA in the membrane phase. The performance of LM‐based separation process is affected by various physical and chemical parameters viz . pH, concentration, stirring rate, temperature, carrier concentration. An optimum operating condition has been identified that would yield the most efficient transport of solute. © 2013 Curtin University of Technology and John Wiley & Sons, Ltd.
