摘要：

The s-triazines atrazine, simazine and cyanzine are easily degraded by UV-irradiation in aqueous titanium dioxide suspensions, because reactive OH radicals are generated under these conditions. A similar reaction can be observed in presence of H202, another OH radical source. In a slow process cyanuric acid is formed as end product. Desethylatrazine and desethylcyanazine were identified as intermediates. Dilute aqueous solutions of atrazine and cyanazine in the ppb-range are effectively decontaminated by photocatalysis. © 1991, Taylor & Francis Group, LLC. All rights reserved.
