丁草胺在水环境中降解规律的研究

摘要

论述了pH值、微生物、太阳光照和温度对丁草胺在水样中降解的影响。结果表明，影响丁草胺在水环境中降解的因素依次为pH值、微生物、太阳光照和温度。太阳光照的影响程度较低，而pH值、微生物和温度的影响程度较高。水中的OH-会对丁草胺的降解有催化作用，另外，水中存在的微生物可加快丁草胺的降解速率；丁草胺在温度较高条件下降解的速率较快。%Butachlor is a kind of herbicide dosage used widely in China. This paper has studied the effect of pH, microbes, sun light and temperature on the degradation of butachlor in water samples. Results show that sun light has lower effect on butachlor degradation in water while pH, microbes and temperature have higher effect on butachlor degradation,in which OH- ions have catalysis for the degradation of butachlor, the microbes and high temperature can accelerate the degradation of butachlor.
