摘要： Silica dioxide bound graphene oxide (GO-SiO2) was applied as an effective adsorbent for determination and quantiflcation of aflatoxin B-1, B-2 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 B-1, B-2 were 0.17 and 0.05 mu g/L, respectively. The method was successfully applied to the detection of the actual edible oil, the spiked recoveries of aflatoxin B-1 and B-2 were 81.4%-105.3% and the relative standard deviations were 1.3%-8.6%.
