Development of hybrid magnetic nanoparticles aimed to collect crude oil in aqueous environments Conference Paper uri icon

abstract

  • Well-defined, magnetic shell crosslinked knedel-like nanoparticles (MSCKs) with hydrodynamic diameters ca. 70 nm were constructed through the co-assembly of amphiphilic block copolymers of PAA20-b-PS280 and oleic acid-stabilized magnetic iron oxide nanoparticles. These hybrid nanomaterials were designed as sequestering agents for hydrocarbons present in crude oil. Their combination of amphiphilic organic domains, for aqueous solution dispersibility and capture of hydrophobic guest molecules, with inorganic core particles for magnetic responsivity, make these nanomaterials uniquely qualified for oil spill remediation. The employment of these MSCKs in contaminated water resulted in the successful removal of the hydrophobic pollutants at a ratio of 10 mg of oil per 1 mg of MSCK. Using a magnet, the loaded nanoparticles were isolated and through "rinsing" in an ethanol sonicating bath, they were regenerated for reuse with no loss of their loading capacity.
