Recently, a variety of chemical and physical methods are employed to separate ionic materials from complex aqueous. Most of all, membrane pertraction using contactor has been considered as alternative recovery and separation system in field of chemical, petrochemical and medicines because heavy metals, hydrocarbon based materials in contaminants like wastewater can be recovered by pertraction system. Also, pertraction process has characteristics such as ease of operation, lower energy consumption and operational cost, higher selectivity. This work investigates some example of developed membrane and their performance for the application of pertraction process.
