Diaromatic sulfur-containing ‘naphthenic’ acids in process waters

Abstract

Polar organic compounds found in industrial process waters, particularly those originating from biodegraded petroleum residues, include ‘naphthenic acids’ (NA). Some NA have been shown to have acute toxicity to fish and also to produce sub-lethal effects. Whilst some of these toxic effects are produced by identifiable carboxylic acids, acids such as sulphur-containing acids, which have been detected, but not yet identified, may produce others. Therefore, in the present study, the sulphur-containing acids in oil sands process water were studied.
