摘要
以高压汞灯为光源,研究了不同浓度的咪鲜胺在添加了丙酮、双氧水、二氧化钛、富里酸(FA)这4种光敏剂及不同水体中的光化学降解情况。结果表明:咪鲜胺的光解速率与其自身的浓度成反比;供试的4种光敏剂均可加速咪鲜胺的光化学降解。光敏作用的大小顺序为:丙酮>双氧水>二氧化钛>富里酸(FA)。咪鲜胺在供试的3种水体中的光化学降解速率大小为:稻田水>河水>纯水。
Changsha, Hunan 410128） The photo-degradation of prochloraz in different medium solutions which added sensitizers-acetone, titanium dioxide, hydrogen peroxide, organic substance （FA） was studied. The results showed that： ①the photo-degradation rate of prochloraz was in positive correlation with its concentration in water②all the 4 sensitizers could accelerate the photo-degradation of prochloraz, in order of acetone 〉 titanium dioxide 〉hydrogen peroxide 〉organic substance （FA） ; ③the photo-degradation rate of prochloraz in water was in order of paddy water〉river water〉pure water.
