流动注射——荧光法测定水样中敌敌畏含量
Determination of DDVP in Water Samples with Flow Injection—Fluorometry Technique
Abstract
有机磷农药敌敌畏(ddVP)在过硼酸钠的作用下可将胺类化合物氧化成可发荧光的产物。本研究根据这一原理,建立了定量测定这类农药的流动注射——荧光分光光度法。该方法具有分析速度快、操作方便、重现性好、灵敏度较高等特点。 Indole can be oxidized by some organophosphorus pesticides, such as DDVP, with the existing of sodium perborate, Forming Fluorescent compounds.A technique of Flow injection—Fluorometry was developed For the determination of DDVP in environmental water samples.The technique has the advantages of being Fast, easy, reproducible and relatively sensitive.
