農產品中巴賽松殘留量標準檢驗方法之建立

Establishment of Standard Analytical Methods for Determination of Pesticide Residues in Crops-Tests of Phoxim

摘要


巴賽松(Phoxim)屬有機磷劑類農藥,本研究發展出利用高效液相層析(high performance liquid chromatography, HPLC)檢驗作物中已賽松殘留量之方法。巴賽松以氯仿自米中萃取出,經串聯之矽膠過濾層析管柱(silica cartridge)及矽藻土過濾層析管柱(Florisil cartridge),淨化後以UV 280 nm偵測之,結果添加0.1~0.3 ppm檢體濃度之平均回收率為83.8~84.7%,最低檢出量在米中為0.01 ppm。

Methods using high performance liquid chromatography (HPLC) to determine Phoxim in crops have been developed. Phoxim was extracted from crops, using chloroform; its analysis was determined by UV 280 nm after purification. Studies, performed at 0.1~0.3 ppm fortification levels, showed recovery between 83.8~84.7%. The limit of detection of Phoxim in rice tested was 0.01 ppm.
