A Method for the Separation of Oil from an Aqueous Oil-Detergent Solution Prior to IR Analysis.
Abstract
A procedure was devised to permit the analysis of oil in water solutions in the presence of dissolved detergents using the CCl4 extraction-IR spectrophotometric method. After an initial extraction of the aqueous oil-detergent solution with CCl4, the extract was evaporated on a silica gel column and eluted with CCl4. This procedure effectively removed all the detergent and allowed an interference-free analysis of the CCl4-oil solution with the IR spectrophotometer. About 10% of the initial oil was lost in the procedure. (Author)
