| 摘 要： | 本文研究了阿特拉津在土壤表面的紫外光光解的动力学,并研究了各种因素对光解的影响。实验表明,土壤粒度、湿度、pH值、有机质、腐殖酸和表面活性剂都影响阿特拉津在土壤中的降解。在紫外光辐射下,阿特拉津在土壤表面降解速率常数为(0.09~0.17)/min,光解深度为0.1~0.3mm,半衰期为4~8min。

| Abstract: | Factors affecting photodegradation of Atrazine in the soil surface under UV light have been studied. Its degradation rate constant was determined to be (0.09~0.17)/min, photolytic depth 0.1~0.3 mm and half-life 4~8 min. The results show that soil granule size, pH, humidity, organic matter, humic acid and surfactant all could affect the photolysis of Atrazine in soil. |
