Catalysis and Sensitization in Photochemical Degradation of Triazines
Original language description
The photocatalyzed and photosensitzed degradation of several triazine herbicides (atrazine, propazine, simazine) and of two atrazine metabolites (desethylatrazine and desisopropylatrazine) was investigated under well defined laboratory conditions simulating conditions in natural water bodies. Among metal ions, manganese, cupric and ferric ions were studied. Ferric ions have been found the most effective for triazine degradation. It was shown that they play the rol of the photocatalyst in the reaction systems. Among triazines, atrazine was most readily degraded under all conditions investigated in teh present study. In the photocatalyzed reactions in neutral or acidic pH, as well as in photosensitized reaction where anthraqunonesulphonate was used asa sensititer. Neither catalyzed nor sensitized photochemical degradation preceed via the microbial metabolites desethylatrazine and desisopropylatrazine.
