Paper Abstract

We propose the method of water quality monitoring on the base of resonance Raman and fluorescence spectroscopy. For exciting of second emission from the water samples we have used pulsed copper vapor laser, working at high frequency (104Hz) repetition of short (20 ns) pulses of generation in visible (510,6 and 578,2 nm) region with the average power 1 - 10 W and peak power -- 104 - 105 W. With the help of nonlinear crystal the visible laser emission was transformed to ultraviolet region. In Raman spectra of water solutions we have observed a number of peaks, related to internal and external vibrations of water molecule and some additional peaks, connected with soluted aromatic substances. Our technique permitted to receive the spectra of secondary emission from water samples with different concentration (beginning from 1 ng/L) soluted aromatic compounds and the mixtures of H2O-D2O. We also present the results of analysis of the properties of a number of water filter, cleaning the water from imperfections.
