The aim of this study is to verify the possibility of detecting oil in the bottom sediment using a fibre optic system. The presence of oil is assessed on excitation-emission spectra obtained from spectral fluorescence signals of the sediment sample. A factory spectrofluorometer coupled with an experimental fibre optic measurement system was used. During the determination of spectra, the fibre optic system is set at a 45° angle to the sediment surface and placed above its surface. The light exciting the fluorescence and the light emitted by the sediment are transmitted in a combined bundle of fibre optic threads. The analysis of excitation-emission spectra of sediments contaminated with oil shows variability of the shapes of fluorescence spectra depending on the type and degree of oil contamination, which indicates the feasibility of the sensor design for detecting oil in the sediment in situ.
本研究的目的是验证使用光纤系统检测底部沉积物中石油的可能性。通过从沉积物样品的光谱荧光信号获得的激发-发射光谱来评估油的存在。使用了一台与实验性光纤测量系统耦合的工厂分光荧光计。在光谱测定过程中，光纤系统与沉积物表面成45°角设置并放置在其表面上方。激发荧光的光和沉积物发出的光通过一束组合的光纤传输。对受油污染沉积物的激发-发射光谱分析表明，荧光光谱的形状因油污染的类型和程度而异，这表明了原位检测沉积物中石油的传感器设计的可行性。
