Oil Spill Remediation Using Magnetic Separation | Journal

Magnetic separation technology was applied to remove dispersants and crude oil from water with magnetite and maghemite Maghemite exhibited rather constant removal efficiency for dispersants regardless of surfactant types while magnetite exhibited higher removal efficiency for anionic surfactant and the efficiency was higher in deionized water than in salty water that contains more ions
