摘要:
建立了一种可快速净化果蔬中有机磷农药残留测定的方法。在 NY/T 761-2008标准的基础上,采用多功能的免疫亲和柱(MycoSep 226 AflaZon+)对杨梅 Myrica rubra,黄瓜 Cucumis sativus,辣椒 Capsicum annuum样品的有机磷农药提取液进行净化,净化过程可在 1 min内钟完成,净化液可直接用于测定,并可明显降低对检测设备的污染程度。试验结果表明,所测定的敌敌畏、丙溴磷、乙酰甲胺磷等 19种常见有机磷农药在 0.02 ~ 1.00 mg?L-1范围内有良好的线性关系,相关系数( r2)均大于 0.999;重现性良好,多次重复测定相对标准偏差仅 0.84%,明显优于标准规定处理方法;低、中、高浓度的加标回收率分别在 85.4% ~ 96.1%,89.7% ~ 97.1%,90.2% ~ 103%之间,总体回收率均在 85%以上。
Abstract:
A multifunctional immunoaffinity columns, MycoSep 226 AflaZon+, were applied to purify the extract of organophosphorus pesticide from Myrica rubra, Cucumis sativus and Capsicum annum, based on the standard of NY/T 761-2008.The process of purification could be completed in one minute, and the purified liquid could be directly determined, that significantly reduced contamination to the devices.The result demonstrated that 19 common organophosphorus pesticides, including dichlorvos, profenofos and acephate, had good linear relations in the range of 0.02-1.0 mg?L-1 with correlation coefficients above 0.999.This method could be repeated many times with standard deviation of only 0.84%.The total recovery rates of low, medium, and high concentrations of samples in the range of 85.4%-96.1%, 89.7%-97.1%, 90.2%-103% were above 85%.
