The determination of 2-methylisoborneol and geosmin in water using fluorescence spectroscopy

Geosmin and 2-Methylisoborneol are responsible for imparting earthy, musty taste and odor qualities to water. The human threshold odor concentrations (TOCs) for 2-MIB and Geosmin vary over a wide range. TOCs of 10ng/1 for Geosmin and 30ng/1 for 2-MIB have been reported. Currently available methods are time consuming and require use of sophisticated technique and expensive equipment. Fluorescence spectroscopy has been successfully used in the identification of many organic compounds. Geosmin and 2-MIB have organic origin. This research explores the possibility of using the technique of fluorescence spectroscopy in the determination of Geosmin and 2-MIB. The excitation and emission wavelengths for peak intensities have been identified for these compounds. An attempt has been made to draw a correlation between the concentration of Geosmin and 2-MIB versus fluorescent intensity
