Investigation of the Adsorption of Model and Oil Sands Process-Affected Water Naphthenic Acids on Graphite
DownloadSpring 2015
Naphthenic acids (NAs) are constituents of bitumen in the oil sands deposits in northern Alberta, Canada. The extraction process of bitumen creates an enormous amount of wastewater called oil sands process affected waters (OSPW). This OSPW contains elevated concentrations of NAs, and other...
