Determination of Caffeine and Benzoic Acid in Soft Drink Samples Using UV-VIS Spectroscopy

Honor Student Determination of Caffeine and Benzoic Acid in Soft Drink Samples Using UV-VIS Spectroscopy

Department: Chemistry
Symposium Year: 2013
Student(s): Elizabeth Nelson
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.
