Application of Fe3O4 magnetite nanoparticles grafted in silica (SiO2) for oil recovery from oil in water emulsions by Elmobarak W.F.

“…Using an MDdose as low as 10 mg/L attained a %ηdem in the range of 93%–94.3% for O/W mixtures with Coil < 2000 mg/L, which slightly decreased to ∼90% for higher concentrations. The reported %Roil (p-value <0.05) was >90 ± 0.1 for tests carried out with pH ≤ 7 and Csur ≤ 0.1 g/L and declined at higher pH and Csur to % 86.5 due to the increase in emulsion stability. …”
