Oil sands process-affected water (OSPW), generated from bitumen extraction in the Canadian oil sands, may require treatment to enable safe discharge to receiving watersheds, as dissolved naphthenic acids (NAs) and other acid extractable organics (AEO), identified as the primary toxic components of OSPW, are environmentally persistent and poorly biodegradable.
Nanoparticles are heavily researched for environmental applications, such as photocatalytic water treatment, however practical separation of nanoparticles from colloidal dispersions remains a critical challenge. Here, we demonstrate a new approach to nanoparticle recovery, combining the advantages of flocculation with magnetic separation to enable simple collection of non-magnetic nanoparticles.
