采用微量化样品处理技术处理蜂蜜样品 ,残留物经正己烷 -丙酮提取后 ,进行液 -液分配净化 ,反相液相色谱法测定氟胺氰菊酯残留量 ,检测波长 2 5 6nm ,外标法定量。测定低限为0 0 0 5mg/kg ,回收率 >85 % ,变异系数 <3%。 Honey samples were treated with micro-sample processing technology. The residue was extracted with n-hexane and acetone, and then liquid-liquid partition was used for purification. The residues of fluvalinate were determined by reversed-phase liquid chromatography. The detection wavelength was 256nm. Legal quantity. The lower limit of determination was 0 0 0 5 mg / kg, the recovery rate was> 85% and the coefficient of variation was <3%.
