(280d) A New Emulsion Liquid Membrane (ELM) Enhanced By Nanoparticles and Ionic Liquid for Recovering Heavy Metals from Wastewater Using a Vanadium Compound As Example.

For the first time established and the effect of nanoparticles and ionic liquid in the ELM (W1/O/W2) on the extraction/recover efficiency of the vanadium as an example of heavy metals from synthetic wastewater, the duration of time for batch extraction/recover and on the stability of the emulsion. The vanadium extraction/recover efficiency has been enhanced noticeably to 99.9% in 30 seconds by us using surface-modified 0.01% (W/W) magnetic Fe₂O₃ nanoparticles (20 to 50 nm) in the W1 phase and 5% (V/V) ([OMIM][PF6) ionic liquid in the organic phase (O), 99.7% in 30 seconds by using 0.01% (W/W) MgO nanoparticles (20 to 50 nm) in the W1 phase and 5% (V/V) ([OMIM][PF6) ionic liquid in the organic phase (O), and 98.8% in 30 seconds by using 0.01% (W/W) Al₂O₃nanoparticles (20 to 50 nm) in the W1 phase and 5% (V/V) ([OMIM]PF6) ionic liquid in the organic phase (O). The emulsion stability was enhanced significantly which give the lowest leakage to 84% for more than 3 days. The outcomes of this study can be extended to the removal of hydrocarbons, polar pollutants, and other heavy metals from industrial wastewater and water.
