【摘要】 本文报导了pH和温度对呋喃丹在水中降解影响的初步研究,通过测定不同pH和不同温度下,水中呋喃丹的水解速率和半衰期,发现在25℃下,当pH=8.0时,其水解半衰期为7.0天;pH=7.0时,其半衰期为29.1矢;PH≥8.0时。水解速度加快;pH≤7.0时,水解速度趋于缓慢。升高温度时也促进水解反应,特别是t>25℃时。反应温度系数(Q)为2～4。更多还原

【Abstract】 The effect of pH and temperature on hydrolysis of carbofuran was studied.The test results found that the hydrolytic half-life of carbofuran was 7 and 29.1 days within pH = 8.0 and 7.0 at 25℃,respectively,and when pH≥8.0,the hydrolytic rate of carbofuran increased,while pH≤7.0,it slow down and the decomposition of carbofuran was also promoted by increasing temperature,the coefficient of reacting temperature(Q)was 2-4,更多还原
