环境样品中敌百虫的流动注射化学发光法测定及反应机理探讨
摘要:
利用敌百虫在碱性介质中能够增敏鲁米诺-铁氰化钾体系产生的化学发光性能,建立了一种测定敌百虫的流动注射化学发光分析新方法,并对反应机理进行了探讨.在最佳实验条件下,对实际环境水样和蔬菜样品中残留的敌百虫进行测定,结果显示,其加标回收率在86.4%~94.8%之间,相对标准偏差为1.03%~1.83%;该方法的线性范围为5×10-7~5×10-3 g/L,检测限为1.13×10-7 g/L.
Based on the enhancement of trichlorfon on chemiluminescence of the luminol-K_3 Fe(CN)_6 system in alkaline solution,a novel chemiluminescence method was developed for determination of trichlorfon with flow injection technique,and the possible mechanism was also discussed.The trichlorfon in actual waster and vegetables were successfully determined under the optimal conditions with the recovery of standard addition of 86.4%-94.8%.The relative standard deviation was 1.03%-1.83%.The linear standard curve of this new method was from 5×10(-7) to 5×10(-3) g/L and the detection limit was 1.13×10(-7) g/L.
