摘要
残留在水环境中的农药受到各种生物和非生物因素的影响,会发生复杂的蓄积和降解行为。通过对国内外关于水环境中农药的水解的影响因素和降解机理研究进行总结和归纳,综述了农药的水解动力学规律及水解机理,给出了综合性结论,即农药的水解机理主要是亲核取代反应历程。在一定的温度和pH值条件下,农药的水解遵从一级反应动力学规律,水环境的pH值决定了农药水解的反应速率。
The extensive use of pesticide in many fields, such as modern intensive and highly effective agriculture, sanitation and epidemic prevention, city building, virescence construction and so on, have made great contribution to the development, and led to pollution of the environment. Pesticide retaining in water environment can experience complex behavior of accumulation and degradation resulting from the influence of all kinds of biotic and abiotic factors. Domestic and international research in hydrolysis of pesticide in water environment has been summarized and induced in this paper.
