Abstract

A method to determine the amount of oil, including dispersed oil, in water at low levels wherein a surfactant is first mixed with water which may contain dispersed oil, the surfactant comprising a non-aromatic surfactant able to solubilize into water the particular oil being tested for, and comparing the emission fluorescence of the surfactant/water mixture to previous correlations drawn between known amounts of oil in water and their emission fluorescence under similar conditions.
