摘要:
使用气相色谱、核磁共振仪考察了乐果、甲胺磷农药分别在室温、45℃ 加紫外光照、自然条件下的衰减行为。实验结果 表明: 乐果、甲胺磷溶液在室温条件下经20 天后基本不变; 在每天10 h 的紫外光照和45 ℃条件下, 经过20 天从2 000 mg/ kg 分别衰减至1 010 mg/ kg 和841 m g/ kg; 在自然条件下、喷洒在青菜上的农药衰减较快, 经过11 天甲胺磷和乐果分别衰减至 41.8 mg/ kg 和3.2 mg/ kg。
Abstract:
The attenuate behavior of methamidophos and dimethoate organophosphorus pesticides were observed by the means of capillary gas chromatographic and 1 H- NMR. The attenuate data varied w ith different conditions. At the room temperature, the methamidophos and dimethoate in w ater almost staied unchanged within 20 days. But w hen they w ere left under the 45℃ ; and UV lighting up for 10 hours per day in 20 days, their density would reduce from 2 000 mg/ kg to 1 010 mg/ kg and 841 mg/ kg respectively. In natural condit ion, methamidophos and dimethoate sprayed on the green vegetables reduced fast to 40.8mg/ kg and 3.2 mg/ kg respect ively within 11 days.
