| Summary: |
The paper presents the kinetics of pyrene and chry-sene degradation that occurs in the aqueous environment under the influence of sunlight. Reaction order, rate and rate constants were determined. The research carried out showed the processes of pyrene and chrysene degradation in the aqueous environment under the conditions of the experiment to be homolytic first-order reactions proceed-ing via similar reaction rate constants. The half-lifes of the examined PAHs were also determined. Based on measurements of carbon and hydrogen atomic overcharge in the molecules of the examined compounds, the privi-leged positions in the molecule were found, at which the reactions of substitution may be expected. |
