Formerly classified as naphthenic acids, “naphthenic acids fraction compounds” (NAFC) have become the subject of increasing research, in particular in view of their ubiquitous presence in the Canadian oil sands of Northern Alberta and oil sands process-affected waters (OSPW). NAFC, defined herein as...
