Functionalization of silica-coated magnetic nanoparticles as powerful demulsifier to recover oil from oil-in-water emulsion
Published 2021“…The Fe–Si-MNP were prepared with differing silica layer thicknesses (5 nm [Fe–Si-1], 8 nm [Fe–Si-2], 10 nm [Fe–Si-3], and 15 nm [Fe–Si-4]) and tested for the percentage of oil separation (%Soil) under different dosages (DMNP), oil concentration (Doil), surfactant dosages (Dsur), and pH. …”
