Determination of Profenofos in Blood by Gas Chromatography

Objective Study of blood organophosphorus pesticides by gas chromatography,improve detection process,optimizing the detection of conditions,establish simple and efficient extraction and purification method is accurate,rapid and sensitive detection method Chromatography.Methods Of blood poisoning after extraction with ethyl acetate,using capillary gas chromatography to determine their contents.Results Analysis of the detection limit of 0.8ng,the low,middle and high concentrations of recoveries is 95.4%±5.85%,91.2%±11.5% and 92.8%±5.5% resperctively.Conclusion The method is sensitive,accurate,reliable and suitable for human blood Proenofos testing.
