百菌清水解的影响因素研究
0
()
摘要:
研究温度、pH、表面活性剂十二烷基苯磺酸钠(SDBS)和水质类型对百菌清水解速度的影响.结果表明,温度和pH对百菌清的水解速率影响显著,温度高,水解加快,pH值越高,水解越快;表面活性剂十二烷基苯磺酸钠可加快百菌清的水解反应速率,但十二烷基苯磺酸钠的浓度对百菌清的水解速度影响不显著.百菌清在不同水质中的水解速率不同,在地下水和巢湖水中比在蒸馏水中水解快.

Study on Factors Influencing the Hydrolysis of Chlorothalonil
()
Abstract:
The effect of sodium dodecylbenzenesulfonate(SDBS), temperature, pH and different water types (distilled water, ground water, Chao lake water) on the hydrolysis of chlorothalonil was studied. Temperature and pH had marked influence on the hydrolysis rate of chlorothalonil.The hydrolysis rate of chlorothalonil increased with the increase of solution temperature and pH. SDBS could enhance the hydrolysis rate of chlorothalonil, but the concentrations of SDBS had no marked influence on the hydrolysis rate of chlorothalonil. The hydrolysis rate of chlorothalonil in different water was different, the hydrolysis rate of chlorothalonil in ground water and Chao lake water was quicker than that in distilled water.
Key words:  chlorothalonil,hydrolysis,temperature,water quality,pH,sodium dodecylbenzenesulfonate
