Abstract

Photophysical properties of the widely used fluorescence tracers eosin, uranin and pyranine were determined in water at different pH. In order to elucidate the potential of LIF spectroscopy for in-situ measurements, calibration curves of uranin in different waters have been measured and the influence of other components in natural waters and of soil on the LIF signals was determined. Furthermore, LIF spectroscopy was applied to the investigation of sorption processes in water/soil-mixtures and of transport processes in soil columns.
