Abstract

4-nitrophenol is one of the phenolic compounds found in industrial wastes that needs to be removed from treated wastewater. Emulsion liquid membrane (ELM) has been introduced as a developing technology for advanced wastewater and water treatment. This emerging technology of treatment can be intensified by strategically adding nanoparticles to organic membrane phase (O). To facilitate the industrial implementation of ELM with nanoparticles, we used magnetic iron nanoparticles added to the organic phase (O) in order to recover them by a magnet for reuse. This also assists in de-emulsification step. The results show that with the use of 1% (W/W) of magnetic nanoparticles of 30-60 nm, the removal efficiency increased from 54.48% without nanoparticles to 97.4% with nanoparticles in reaction time of 1.5 minutes, and both the stability and extraction activity of ELM are enhanced. The outcomes of this work can be extended to other hydrocarbons and polar pollutants removal from industrial wastewater and water.
