Abstract

Fluorescent methods using Raman scattering signal as an internal standard are widely applied for environment remote control of dissolved organic matter (DOM) in water. In this paper temperature variations, ultraviolet irradiation influence on exitation and emission spectra of water samples have been investigated. Photochemical processes in DOM under laser excitation and the effect of fluorescence saturation have been studied
