The contribution of fluorescence to measurements of light scattering in oil-in-water emulsions

Mineral oil emulsion species and concentration prediction using multi-output neural network based on fluorescence spectra in the solar-blind UV band

“…The experimental results demonstrate that solar-blind UV fluorescence can provide new ideas and application prospects for outdoor, all-day, and all-weather fluorescence monitoring. 25,31…”

“…In order to obtain the trend in the variation of the fluorescence with concentration, 25 the fluorescence spectra of oil-in-water emulsions with ten concentrations from 20 ppm to 20 000 ppm were measured, as shown in Table 2. The “ppm” here represents parts per million of a volume ratio.…”

“…The oil-in-water emulsions with low concentrations (according to the experimental results, concentrations less than The experimental results demonstrate that solar-blind UV uorescence can provide new ideas and application prospects for outdoor, all-day, and all-weather uorescence monitoring. 25,31 The comparison of selected long-wave uorescence peaks and day-blind UV uorescence peaks can clearly show the nonlinear trend in the uorescence changes. As shown in Fig.…”

Estimation of Emulsified and Dissolved Oil Content in Seawater

“…Determination of hydrocarbon content in these samples was carried out using comparative fluorescence method [17] on spectrofluorimeter Shimadzu RF-5301PC. All samples were excited by the light wavelength 240 nm, and the emission of fluorescence signal was measured at the wavelength 320 nm.…”
