Abstract
The biosynthesized magnetic metal nanoparticles for oil spill remediation are magnetic nanoparticles capped with an extract of. The magnetic nanoparticles are formed by co-precipitation of ferric chloride hexahydrate and ferrous chloride tetrahydrate in an ethanol solution of the extract with the dropwise addition of ammonium hydroxide to raise the pH to between 8 and 11. The extract may be an extract of the aerial parts ofin a low polar extraction solvent, such as an n-alkane solvent or mono-di-, or trichloromethane. The extract is hydrophobic, improving dispersion of the magnetic nanoparticles in oil spills in seawater, resulting in 90% removal of oil for a 1:10 ratio of nanoparticles:oil by weight.
