中文摘要：

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^-5g／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^-8g／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％．

英文摘要：

A new flow injection chemiluminescence （FI-CL） method for the determination of dichlorvos was developed. The method is based on the CL reaction of dichlorvos with luminol-H2O2 in 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 × 10^ -8 - 2.50 × 10^ -5 g/mL, with a detection limit of 2.20×10^ -8 g/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 determination of dichlorvos residues in crops and vegetables.
