| 摘 要： | 目的]探讨吡蚜酮在土壤中的吸附行为。方法]采用批量平衡试验方法,研究了杀虫剂吡蚜酮在5种不同土壤中的吸附行为,并探讨了土壤理化性质对吡蚜酮在土壤中吸附的影响。结果]吡蚜酮在不同性质的土壤中,吸附量不同。土壤pH是影响该农药在土壤中吸附的主要理化性质,吡蚜酮在5种土壤中的吸附能力大小顺序为河南褐土〉湖南红壤〉云南粘壤〉山东褐土〉湖南河潮土。Freundlich方程能较好地拟合吡蚜酮在土壤中的吸附等温线。吡蚜酮在5种供试土壤中的吸附常数（Kf）在6.2201～69.3760,自由能在14.70～21.12 kJ/mol,表现为物理吸附过程。结论]为评价吡蚜酮对土壤、地下水的危害的可能性提供了参考。

| Abstract: | Objective] The paper was to explore the adsorption behavior of pymethrozine in soils.Method] The adsorption behavior of pesticide pymethrozine in five different types of soil was studied using bath equilibrium method,and the effect of soil physicochemical properties on adsorption of pymethrozine in soils was also explored.Result] The amount of pymethrozine adsorbed by soils was different in the soils with different properties.Soil pH was the main physicochemical property affecting adsorption of the pesti... |
