Abstract
The presence manuscript conducted on lead removal from industrial wastewater using an emulsion liquid membrane method (ELM). The developed ELM consisted of ionic liquid 1-Methyl-3-octylimidazolium hexafluorophosphate ([OMIM]PF6) in membrane phase is used as a stabilizer to provide sufficient stability of emulsion. Other ingredients for emulsion preparation are solvents (kerosene), surfactant (Span 80), extractant [di-2-ethylhexyl phosphoric acid (D2EHPA)], and sulfuric acid (H2SO4) as an internal receiving phase. Recently, experiments investigated the parameters' effects on % removal of lead(II) and ELM techniques such as homogenous speed, surfactant and extractant concentrations, internal to membrane phase ratios, agitation speed, treated ratios, pH of external phase, and ([OMIM]PF6) concentrations. At the best conditions, results showed the stabilizing effect of ionic liquid and nanoparticles was sufficient enough for % removal of lead(II) during the first five minutes of the extraction process of therapeutic studies with low turbidity and swelling at the end of experiment.
