Laser diagnostics of humic substances as natural detoxicants and fluorescent indicators of the pollutants in water

Binding constantans of the pyrene and uranyl (which present two classes of ecotoxicants in the natural and effluent water) by the humic substances were evaluated using the method of laser fluorimetry. The influence of these pollutants on the fluorescent characteristics and photophysical parameters of the humic substances acquired with the technique of laser fluorimetry was revealed and thus the perspectives of using humic substances as fluorescent indicators of the pollutants in the water were highlighted.
