Abstract:

We present in this paper the spectra of laser-induced fluorescence (LIF) of organic impurities in drinking water excited by the fourth harmonic of a Nd:YAG laser radiation at 266 nm. We propose to assess the degree of water pollution using the intensity ratio between the fluorescence of an impurity and the Raman band of water (F/R). Water samples, taken at different stages of the technological cycle of water cleaning being employed at the Chistaya Voda Company, convincingly demonstrate the decrease in the content of organic impurities in drinking water during its processing.
