| 摘 要： | 【目的】研究阿维菌素在土壤中的环境行为。【方法】应用平衡法研究了阿维菌素在5种土壤上的吸附特性。【结果】土壤对阿维菌素具有很强的吸附特性，且随着土壤理化性质的差异，土壤对阿维菌素的吸附性有着明显差异；阿维菌素在土壤中的吸附符合Fruendlich方程，其吸附常数Kaf值与土壤有机质含量和粘粒含量呈显著正相关性；阿维菌素在土壤上的吸附自由能为10.9859～25.1538 kJ•mol-1。【结论】阿维菌素在土壤上的吸附主要是物理吸附；表面活性剂吐温－80对水稻土、菜地土和山地红壤上吸附的阿维菌素具有显明的增溶作用，而对山地黄壤和盐碱土则有着增加土壤对阿维菌素的吸附能力的影响。 |

| Abstract: | Adsorption of abametin in 5 different soils was studied by batch equilibration technique. The result showed that soils had strong adsorption of abamectin, which, however, varied with the different properties of the soil tested. The isotherm data were fitted to Fruendlich equation, The Kaf values increased with increasing organic matter and clay content of soil, the correlative coefficient of Kaf values and organic matter and clay content of soil were significantly positive .The free energy of sorption ranged from 10.9859 kJ/mol to 25.1538 KJ/mol indicates that the spontaneity of the given sorption process of abamectin in soils. |
