RESUMEN
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%.
