Capillary electrophoretic study of atrazine photolysis



Capillary electrophoretic study of atrazine photolysis



Journal of Chromatography A 709(1): 215-225



Capillary electrophoresis in its free solution mode (FSCE) has been used as a rapid analysis tool for the quantification of hydroxytriazines during the photodegradation of atrazine under nitrogen and oxygen atmosphers in the presence or absence of humic substances in aquatic media. Hydroxyatrazine was found to be the main photodegradation product. The presence of dissolved humic substances influenced the photodegradation pathway of atrazine by dealkylation reactions. FSCE has been found effective in the separation of the cationic hydroxytriazines from the anionic humic polyelectrolytes during the analysis without cleanup procedures.
