| 摘 要： | 对高压汞灯下,苯噻草胺在甲醇、乙腈、异丙醇和水中的光化学降解以及丙酮对其在水中光解的影响进行研究.结果表明,在甲醇、乙腈、异丙醇和水中,苯噻草胺光降解显著,半衰期分别为5.34、5.03、30.26和5.73 min;在水中,丙酮对其光解有敏化作用,且敏化作用与丙酮的剂量有关,在低浓度时敏化不明显. |

| Abstract: | The photodegradation of mefenacet in various solvents under high-pressure mercury lamp was studied. It was indicated that in methanol, acetonitrile, isopropyl alcohol and pure water, the photolytic rates of Mefenacet were rapid and the half-lives were 5.34, 5.03,30. 26 and 5.73 min respectively. The photolysis of Mefenacet in water was sensitized by acetone, but the sensitive effect was relevant to the concentration of acetone added to the solution. At low concentration, it was not obvious. |
| Keywords: | mefenacet organic solvents photodegradation photo-sensitive |
