Abstract

In this study, a broadband light source (visible and ultraviolet) was used to name minerals via fluorescence spectra and estimate slick oil thickness, ranging from sub-millimetres, using the reflecting spectrum technique. Using a fluorescent technique, we obtained fluorescence spectra of the samples, converting and processing the signals to produce high-resolution data, which enabled the identification of the types of dissolved elements and oil slicks in the Tigris River, highlighting pollution sources and potential control measures. This system aims to show the faint signal in fluorescence samples collected from the cooling system outlet water throughout the refining process from AL-Dora (Baghdad) and Baiji (180 km north of Baghdad) refineries on the Tigris River. A simple optical technique is proposed for remote testing to figure out slick oil thickness and detect dissolved minerals in river water for the first time in Iraq. Accurate detection of minerals and slicks is achieved as mineral oil stimulated by UV light emits visible wavelengths, with a detection limit of 0.5 ppm. Laboratory measurements of sub-millimetre oil slick thickness were conducted, with fluorescence detected using systems running at various excitation wavelengths. The research focuses on measuring the thickness of oil slicks on water surfaces and differentiating between distinct types of mineral pollutants. This capability to distinguish pollutants based on their physical and chemical characteristics introduces a novel aspect to the study, highlighting the technique's versatility in analysing complex mixtures
