摘要
以鸡脑为酶源提取乙酰胆碱酯酶,利用酶抑制分光光度法检测蔬菜中有机磷农药残留量.用此方法测定了对硫磷、辛硫磷、氧化乐果三种农药,结果满意,回收率分别达到97%,101%和99%.
Acetylcholinesterase was extracted from chicken brain, and the organophosphorus pesticide residues were determinated by enzyme inhibition spectrophotometry. The method presented in this paper has been applied in the determination of parathion, phoxim, omethoate with satisfactory results. Recovery of parathion, phoxim, omethoate were found to be 97%, 101%, 99%, respectively.
