【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、p H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]:In order to clarify the hydrolysis kinetics of cyclophosphamide, the effects of temperature, p H value, surfactants and different kinds of water on the hydrolysis of cyclophosphamide were investigated by laboratory simulation test. The results showed that the hydrolysis rate of cyclophosphamide was accelerated with the increase of temperature, the degradation of cyclophosphamide was the fastest under alkaline conditions, and the hydrolysis of cyclophosphamide was inhibited by sodium dodecyl sulfonate (sodium dodecyl sulfonate,SDS). When the concentration of humic acid was lower than 1 mg L-1, the hydrolysis of cyclophosphamide was promoted, and the hydrolysis of cyclophosphamide was inhibited when the concentration was higher than 1 mg L-1. The order of hydrolysis rate of cyclophosphamide in different water bodies was as follows: the degradation rate of cyclophosphamide was significantly higher than that of indoor simulation under natural conditions.
