OIL FINGERPRINTING BY PHOSPHORESCENCE : A FEASIBILITY STUDY

Phosphorescence of oil was studied by means of a Baird- Atomic Fluorispec fluorescence spectrophotometer, Model SF-100, with a phosphoroscope accessory. Instrumental settings were determined for phosphorescenece, and solvent effects were studied, including the effects of glass viscosity, polarity, and enhanced intersystem crossing due to the heavy atom effect. Solvents tested included methylcyclohexane, perfluorodimethylcyclohexane, tetrahydro-2-methylfuran, ethyl iodide, and pentane. A solution of 1 percent bromoform in methylcyclohexane produced much more structure in the phosphorescence spectra of crude oils than did pure methylcyclohexane. A standardized phosphorescence method was successfully applied to an actual oil spill.
