Bio-oil is a renewable fuel source with the potential to replace fossil fuels. Characterization of the composition of bio-oil is of interest to many scientists. Bio-oil is composed of hundreds of molecules making characterization a difficult and time consuming task. Various methods have been investigated as viable methods for separation and characterization. In this work, UV-Vis Spectroscopy is utilized to investigate the aromatic content of various bio-oils. Standard addition is method where a known amount of standard is added to a sample of interest. Using the Beer-Lambert law, the graph can be extrapolated to quantify the amount of target compound in a mixture. Results indicate this method is a viable strategy for quantifying target compounds and provides preliminary quantitative data on the aromatic content of bio-oils tested.
