Stability of primary emulsion assisted with nanoparticle in emulsion liquid membrane process for zinc extraction

In the present work, primary water-in-oil (W/O) emulsion consisting blended surfactant and nanoparticle is used for the improvement of ELM stability for zinc extraction. The components used in ELM were di-(2-ethylhexyl)phosphoric acid (D2EHPA) and bis(2,4,4-trimethylpentyl)thiophosphinic acid (Cyane...
