【摘要】 通过高效液相色谱法分析了过碳酸钠对甲氰菊酯和高效氯氟氰菊酯降解效率的影响因素。结果表明,随着过碳酸钠量的增加和温度的升高,农药的降解率增大;在碱性条件和酸性条件下,农药的降解率比在中性条件下大。通过对菊酯农药在酸性、中性、碱性条件下动力学的研究,证明菊酯农药降解的动力学方程都基本能满足一级动力学方程,且降解速率常数由小到大依次为k中性<k酸性<k碱性。更多还原

【Abstract】 The paper has studied the various factors influencing the degradation process of pytethroids pesticides by high performance liquid chromatography.The results show that,the degradation efficiency is higher under more dosage of the SPC,higher temperature,as well as acidic and alkalescent condition.The degradation kinetics is a first-order reaction.更多还原
