摘要/Abstract

摘要： 研究了农药敌敌畏在碱性介质中与鲁米诺过氧化氢产生化学发光的特性，发现非离子表面活性剂聚乙二醇辛基苯基醚（乳化剂OP）对该反应有明显的增敏作用，建立了鲁米诺过氧化氢OP体系测定敌敌畏的流动注射化学发光的新方法. 结果表明, 敌敌畏浓度在8.00×10－8～2.50×10－5　g/mL与化学发光强度有良好的线性关系，该方法的检出限为2.20×10－8　g/mL. 3种样品加标准回收率为94.0%～104%，相对标准偏差为4.27%～5.75%.

Abstract: A new flow injection chemiluminescence(FICL) method for the determination of dichlorvos was developed. The method is based on the CL reaction of dichlorvos with luminolH2O2in the alkaline medium and sensitized by the nonionic surfaceactive agent polyoxyethyle octyl phenyl ether. The results show that the CL intensity is linear to the concentration in the range of 8.00×1 0－8～2.50×10－5　g/mL， with a detection limit of 2.20×10－8g/mL.　The standard addition recovery and relative standard deviation (n=6) of three samples were 94.0%～104% and 4.27%～5.75%, respectively. This method has been applied to the determ ination of dichlorvos residues in crops and vegetables.
