摘要
采用田间土壤,在人工光解装置箱中研究了在紫外光照射下土壤表面阿特拉津的光解行为以及影响其光解行为的因素。实验测得阿特拉津的光解速率常数为0.0953～0.1864min-1,光解深度为0.10～0.23mm,半衰期为3.7～7.3min。研究结果表明,土壤粒度、pH值、有机物含量、土壤湿度、腐植酸含量及表面活性剂含量均会对阿特拉津在土壤表面的光解产生影响。
The photolysis of atrazine on soil s urface under ultraviolet and factors affecting photolysis were studied in the present study.A rate constant of 0.0953～0.1864min -1 ,photolytic depth of 0.10～0.23mm an d half -life of 3.7～7.3min were de-termined.The result showed that soil granularity,pH,organic content,humidity,content of humic acid and s urface -active agents could affect the photolysis of atrazine in soil.
