Faculty Mentor(s): Dr. Matthew Crawford
Caffeine and benzoic acid, commonly found in soft drinks, were qualitatively and quantitatively determined using UV-VIS Spectroscopy. Calibration curves utilizing Beer’s Law were prepared for both a series of caffeine and benzoic acids standards. The calibration curves were used to then determine the concentration of caffeine and benzoic acid in the various drinks. All samples were analyzed on a UV-Vis spectrometer measuring at the determined λmax for each chemical specie.
