Abstract
Atrazine and glyphosate, two widely used herbicides, is traditionally detected through liquid/gas chromatography or IR spectroscopy. However, these methods are either time-consuming or (Groenewold et al., 1997; Clegg et al., 1999), so fluorescence spectroscopy is investigated as a more cost and time efficient alternative. Literature values of the optimal wavelengths of glyphosate was found to be 230 nm excitation and 450 nm emission (Schuster, 2000), while optimal wavelength of atrazine was found to be 350 nm emission. Known concentrations of atrazine and glyphosate from 10 to 40 mg will be analyzed with a fluorescent spectrophotometer to develop a calibration curve. This calibration concentration curve will then be used in the future to determine the concentrations of the species in local water samples, collected by the Biology Department at EKU.
