摘要: 为明确环氟菌胺的水解动力学规律，采用室内模拟试验方法，探究了温度、pH值、表面活性剂和不同种类水体对环氟菌胺水解的影响。结果表明：随着温度的升高，环氟菌胺的水解速率加快；环氟菌胺在碱性条件下降解最快；十二烷基磺酸钠(sodium dodecyl sulfonate, SDS)抑制环氟菌胺的水解；腐植酸的浓度低于1 mg·L^-1时促进环氟菌胺的水解，浓度高于1 mg·L^-1时抑制环氟菌胺的水解；环氟菌胺在不同水体中的水解速率顺序为：海水 > 江水 > 河水，环氟菌胺在自然条件下的降解速率显著高于室内模拟条件。

Abstract: The hydrolysis characteristics of cyflufenamid was investigated in different kinds of water matrices under different conditions (i.e. temperature, pH value and sodium dodecyl sulfonate (SDS) ) based on indoor simulation test method. The results showed that the hydrolysis rate of cyflufenamid was gradually enhanced with temperature increasing. Additionally, the hydrolysis of cyflufenamid was promoted in alkaline condition. While, it was inhibited by SDS at the concentration of 100-900 mg·L^-1. Furthermore, it was promoted at lower concentration (1 mg·L^-1) of humic acid, and was restricted at high concentration (more than 1 mg·L^-1). Interestingly, the hydrolysis of cyflufenamid in three water matrices showed the following order: seawater > riverwater >streamwater, and the degradation rate of cyflufenamid was faster in natural conditions comparing to indoor conditions.
