摘要:
摘要:建立了一种测定大米中稻瘟灵残留量的气相色谱法。 样品经乙腈提取, 提取液浓缩后, 经中性氧化铝固相萃取柱与氟罗里硅土固相萃取柱净化, 用配有电子捕获检测器的气相色谱仪测定, 外标法定量。稻瘟灵线性范围为 0.0025～ 0.250 0μg·mL -1 , 其相关系数和回归方程分别为 R 2 =0.9996, y = 57194.44x-71.82。 样品平均加标回收率为87.8%～ 106.7%, 相对标准偏差为 4.35%～ 5.91%。方法的最低检出限0.005 mg·kg -1 。
Abstract:
Abstract:The gas chromatographic method was used to determine isoprothiolane residues in rice.The isoprothiolane residuein the test sample was extracted with acetonitrile.After the extracts was evaporated, the residues were cleaned up by solidphase extraction(SPE)with a neutral aluminum oxide cartridge and a florisil cartridge.The residue was determined by GCwith ECD-detector,using external standard method.The liner range was 0.002 5～ 0.250 0μg·mL -1 for isoprothiolane.Thecorrelation coefficients were 0.9996 for isoprothiolane.The regression equation was y= 57194.11x-71.82.The average re-coveries of isoprothiolane in spiked samples ranged from87.8%～ 106.7%, and the relative standard deviations were between4.35%～ 9.91%.The limit of detection was 0.005 mg·kg -1 in method.
