The present work seeks to explore the field of application of supported ionic liquid membranes for removal of phenol, extraction and selective separation of heavy metals, including chromium and vanadium. The mass-transfer coefficient depends strongly on the concentration and the hydrodynamics of the system and can, therefore, be varied and optimized. As a result, the removal process must be hydrodynamically characterized, and a number of experiments has to be performed to establish adequate conditions. The hydrodynamics, and the chemical and physical parameters characterize a liquid membrane permeation process. A good prediction on the process behavior could be achieved by applying the parameters which describe the system and by considering how the separation is affected, and the extent of the impact caused by these parameters.
