PICKERING EMULSION LIQUID MEMBRANE STABILIZED BY MAGNETIC NANO-Fe3O4

Significant features of the Pickering emulsion liquid membrane (PELM) as innovative trend of the traditional emulsion liquid membrane (ELM) such as simple operation, fast process, high stability and easy de-emulsification process have gained extensive responsiveness in the recent years. PELM consists of an kerosene as the diluent, nano-Fe3O4 particles as a stabilizing agent and NaOH in the internal phase that are used to remove ciprofloxacin (phenol) from wastewater. This paper comprises simultaneous studies of emulsion stability and extraction efficiency through various parameters, including external phase pH, internal phase concentration and extractant concentration. The results confirm that PELM is a very effective technique to extract more than 96% of phenol without significant emulsion breakage after a contact time of 9 mins.
