Experimental studies of efficient sensing fluorescence radiation bands to detect oil and petroleum product spills

Abstract

Abstract We have experimentally studied the laser-induced spectra of petroleum products at the excitation fluorescence wavelength of 266 nm. The paper depicts a schematic diagram of the laboratory setup, gives data resulted from processing of laser-induced fluorescence spectra, and shows that, in comparison with spectra of petroleum products, the laser-induced fluorescence spectra of oil have a shift toward the longer wavelength spectral region and a far wider spectral bandwidth. For oil, an efficient band of sensing fluorescence radiation, is of ~ 390 – 600 nm in average. For gasoline, an efficient band of sensing fluorescence radiation has a significant shift toward the shorter wavelength region (~ 320 – 360 nm) as compared to the efficient sensing fluorescence radiation band for diesel and engine oils (~ 330-395 nm).
