dc.description.abstractCrude petroleum oils are complex mixtures of different compounds (mainly organic), which are obtained from an extensive range of different geological sources. the fluorescence of crude petroleum oils derives largely from the aromatic hydrocarbon fraction, and this fluorescence emission is strongly influenced by the chemical composition (e.g., fluorophore and quencher concentrations) and physical characteristics (e.g., viscosity and optical density) of the oil. the fluorescence spectroscopy (FS) is increasingly used in petroleum technology due the availability of better optical detection techniques, because FS offers high sensitivity, good diagnostic potential, and relatively simple instrumentation. in this work we analyzed crude petroleum at different dilution in Nujol, a transparent mineral oil. the main objective of this work was to verify the possibility to measure crude oil emission spectroscopic without use of volatile solvents. the mixtures of nujol with different -crude oil concentrations were measured with a 10 mm optical path cuvette thus simplifying the fluorescence spectroscopy signal detection. the emission spectra were obtained by exciting the samples with a 400 W Xenon lamp at 350 nm, 450 nm and 532 nm. the emissions of the samples were collected perpendicularly with the excitation axis.en
