以二氧化硅-氧化石墨烯复合物为固相萃取材料,建立了植物油中黄曲霉毒素B1、B2的高效液相色谱(HPLC)检测方法。优化的条件为:复合材料的最佳用量为0.15 g,最佳萃取时间20 min,洗脱溶剂为乙腈,洗脱次数为2次。结果表明,在优化条件下,建立的二氧化硅-氧化石墨烯复合物固相萃取-高效液相色谱法对黄曲霉毒素B1、B2的检出限分别为0.17和0.05μg/L。将本方法应用于植物油实际样品的检测中,加标回收率在81.4%~105.3%之间,相对标准偏差为1.3%~8.6%。
以二氧化硅-氧化石墨烯複閤物為固相萃取材料,建立瞭植物油中黃麯黴毒素B1、B2的高效液相色譜(HPLC)檢測方法。優化的條件為:複閤材料的最佳用量為0.15 g,最佳萃取時間20 min,洗脫溶劑為乙腈,洗脫次數為2次。結果錶明,在優化條件下,建立的二氧化硅-氧化石墨烯複閤物固相萃取-高效液相色譜法對黃麯黴毒素B1、B2的檢齣限分彆為0.17和0.05μg/L。將本方法應用于植物油實際樣品的檢測中,加標迴收率在81.4%~105.3%之間,相對標準偏差為1.3%~8.6%。

Silica dioxide bound graphene oxide ( GO-SiO2 ) was applied as an effective adsorbent for determination and quantiflcation of aflatoxin B1 , B2 in edible oil by HPLC. The optimized conditions were GO-SiO2 0. 15 g, extraction time 20 min, elution reagent acetonitrile, elution cycles two times. Results showed under the optimum conditions, the detection limits of aflatoxin B1 , B2 were 0. 17 and 0. 05 μg/L, respectively. The method was successfully applied to the detection of the actual edible oil, the spiked recoveries of aflatoxin B1 and B2 were 81. 4%-105. 3% and the relative standard deviations were 1. 3%-8. 6%.
