This study investigates the characteristics that can be observed at certain excitation wavelengths through the use of fluorescence spectroscopy. Characterization of samples was performed via TOC, UV-visible spectroscopy, and fluorescence spectroscopy. This research confirms that it is possible to utilize fluorescence spectroscopy with an excitation wavelength of 270 nm to determine the levels of protein-like fluorescence present in a water sample. This confirmation makes it possible to monitor water quality via a probe with a 270 nm LED light for quicker, easier analysis of water quality in the field over periods of time. Further investigation is recommended to refine the equation used to transform the fluorescence data to intensity of protein-like fluorescence.
