Laser-induced fluorescence of bio-organic impurities in water

The fluorescence emission spectra of tap and drinking water, natural and industrial waste water, as well as aqueous solutions of some synthetic oligopeptides and different components of tap water obtained under the excitation by both XeCl ((lambda) equals 308 nm) and KrF ((lambda) equals 248 nm) excimer lasers have been analyzed. The results suggest the applicability of a KrF laser-induced fluorescence for monitoring of tap and waste water.
