Abstract: The membrane liquid (ML) or the organic phase must be immiscible with the feed/receiving phases. Feed phase typically contains solute that needs to be transported across the thin film of LM to the receiving phase. The transport of solute across the LM occurs due to the difference in solubility and diffusivity in the liquid film as well as the concentration gradients in the phases selective separation of the solute is possible if ML is chosen wisely so that only the target solute is soluble and diffusive in the membrane phase. When the solute is not soluble in the selected solvent, carrier/extracts is added in the solvents to increase the solubility of the solute by solute-carrier completion.
