Infrared determination of petroleum oil. Part II. Extraction from water and removal of interferences

Abstract

A brief review is given of the methodologies used in the infrared determination of petroleum oil. Some performance characteristics are presented for a method that measures hydrocarbons after a Florisil column clean-up. Extraction efficiencies were determined for dispersions of gas oil in water for the solvents carbon tetrachloride and Freon 113. The removal of interferences was also studied.
