摘　　要：以氙灯为人工光源,研究莠去津在水中的光化学降解速率。采用高效液相色谱法,对不同p H值水体中莠去津含量进行检测,莠去津在p H=4.0缓冲溶液中未发现光解,在p H=7.0和p H=9.0缓冲溶液中的水解半衰期分别为63.0 h和115.5 h。莠去津在酸性水体中稳定,在中性和碱性水体中易于光解。Xenon lamp was used as an artificial light for the study of the photochemical degradation rate of atrazine in aqueous solution.The content of atrazine in different p H were determined by HPLC. The results showed that the atrazine could not photolysis in p H =4.0 buffer solutions and the photolysis half-lives were63.0 h and 115.5 h in p H=7.0 and p H=9.0 buffer solutions.Atrazine is stable in acidic aqueous solution and is easily photolysis in neutral and alkaline aqueous solution.
