Abstract
We investigated the ethylene glycol, which is the crucial ingredient in the automotive antifreeze coolants, the content of engine oil at various levels of contamination using Fourier transform infrared (FT-IR) spectroscopy and ultravioletvisual spectroscopy (UV-Vis). It is known that glycol in SAE 15W-40 diesel engine lubricating oil has relatively strong signatures in the infrared spectrum, some of which overlap with other molecular bonds that may already be present in engine oil. Therefore, our aim is to correlate this FT-IR data with a UV-Vis spectrograph such that detection of glycol’s presence can be improved significantly
