Time-resolved excitation-emission-spectra for screening of residual waste
For remote sensing of residual waste in water and soil, polycyclic aromatic hydrocarbons (PAH) are of special relevance because of their carcinogenic and mutagenic properties. Due to the native fluorescence of PAH, fluorescence spectroscopy is the method of choice for detection of these molecules. The objective of this work is to employ a combination of static and dynamic fluorescence spectroscopy (ie time-resolved excitation-emission spectra (TEES). The obtained four dimensional data arrays represent fluorescence intensity as a function of time, excitation and emission wavelength, which provide a multitude of information about the excited molecules and their local environment.
