摘要
The mechanisms of the photodegradation of atrazine under direct photolysis and in the presence of two different photocatalysts, TiO2 and Na4W10O32, are investigated by the means of GC/MS, total radioactivity counting, HPLC and TLC analysis on C-14 ring-labelled atrazine solutions. Integration of photo- and biodegradation processes is studied. (C) 1999 Elsevier Science Ltd. All rights reserved.
