摘要
从环境的角度来看,吸附、分布系数、Langmuir和Freundlich模型以及农药的数学评价变得更加有趣。结果表明,茚虫威、吡虫啉和高效氯氟氰菊酯发生伪一级反应。降解速率分别达到0.01、0.07和0.04 / min。而氯虫腈达到每分钟0.00002。这表明这些杀虫剂的浓度仅随时间而下降。因此,每种杀虫剂(DT50)减少50%所需的时间是不同时期的。茚虫威、吡虫啉、高效氯氟氰菊酯和氯虫虫腈的杀伤时间分别为3.2、1.9、10.1和2.3 d。分布系数Kd分别为5.25、1.30、0.562和0.639 mL g-1。说明茚虫威、吡虫啉在土壤中具有迁移性,而高效氯氰菊酯和氯虫腈在土壤中迁移性较差。在Freundlich模型(aF)下,氯虫腈2.82和高效氯氰菊酯2.75比茚虫威0.013 L g-1和吡虫啉0.249 L g-1更适合Langmuir模型(KL)。
Behaviour Study of Four Insecticides using different Mathematical Modeling
The adsorption, distribution coefficient, Langmuir and Freundlich models and the mathematical evaluation of pesticides have become more interesting from an environmental point of view. The outcomes revealed that indoxacarb, imidacloprid, and lambda-cyhalothrin are subjected to the Pseudo-first order reaction (PFO). The rate of degradation was reached, into 0.01, 0.07, and 0.04 a minute respectively. While chlorantraniliprole reached 0.00002 a minute. This indicates that these insecticides are decreasing in their concentrations depending only on the time. Hence, the time required to decrease 50% of each insecticide (DT50) was various periods. The DT50 for indoxacarb, imidacloprid, and lambda-cyhalothrin, and chlorantraniliprole 3.2, 1.9, 10.1, and 2.3 days respectively. The distribution Coefficient Kd as well scored (5.25, 1.30, 0.562, and 0.639) mL g-1 respectively. This indicated that indoxacarb, imidacloprid has a mobility behaviour, while the lambda-cyhalothrin and chlorantraniliprole are less mobile in the soil. In terms of Freundlich model (aF), chlorantraniliprole 2.82 and lambda-cyhalothrin 2.75 are more fit than indoxacarb 0.013 L g-1 and imidacloprid 0.249 L g-1 subjected to the Langmuir model (KL).
