| 摘 要： | 基于杀扑磷对过氧化氧和鲁米诺在碱性条件下化学发光有抑制作用，本文建立了一种杀扑磷的流动注射化学发光（FI-CL）检测方法。杀扑磷在1．0×10^-7-1．0×10^-3g／mL范围内与发光强度呈良好的线性关系，检测限（S/N=3）为7．3×10^-8g,／mL，测定相对标准偏差（RSD）为1．26％，对柑橘样品进行加标回收率测定，回收率在89．5％-92．6％之间。

| Abstract: | A method for the determination of methidathion based on the inhibitionof chemiluminescence(CL) of luminol-H2O2 inbasicmedium by flow-injection CL analysis has been established. The calibration curve waslinear for the methidathion range of1.0×10-7-1.0×10-5g/mL with a detection limit(S/N=3) of 7.3×10-8g/mL and the relative standard (RSD) was 1.26%. The method was applied to the determination of methidathion in orange and the recoveries werebetween 89.5%～92.6%. |
