Lenine Tomsk, 634050,Russia Natural water pollution by organic materials, among of that phenol and its derivatives are the most harmful contamination, increases due to industrial activities and accidents. Resulting from more regulation concerning natural, surface and wastewater, improvements in the existing methods of water treatment and fluorescent analysis, as well as research into new methods are required. In particular, some new techniques have been proposed that utilize UV light of excimer laser. The present study was undertaken in the framework of research needed to increase our knowledge of photolysis mechanism of phenols in water.
Phenol constitutes one of the main pollutants to be removed from wastewater.
It is a very simple organic compounds, easily soluble in water at different condition of acidity. This work present the results of the photolysis of phenol in aqueous solution after high-pressure Hg lamps. The experiments should contribute to a better knowledge of ionic phenol forms participation in phenols phototransformation processes in the liquid phase. The value of basicity pK a inferred from changes of the phenol spectral luminescence properties in a slightly acid solution increases at excitation. These ionic forms can participate in phototransformations as intermediate photoproducts.
