Abstract
Aiming at the problem of false positive detection of the bromate ion chromatography in flour products,a method for bromate by pre column derivatization HPLC determination of flour products was established.Flour products were treated by ultrapure water extraction,filtration and derivative,than analyzed by C18chromatographic column and UV detector.The results showed that,the reaction at 45 ℃ of 60 min derivative with the potassium ferrocyanide-zinc acetate was used to the precipitant solution,had a good linearity in the range of 0.025～1 mg/L.The recoveries were between 87.90％ ～94.80％,detection limit was 0.3 mg/kg and quantitative limit was 1 mg/kg.This method was less interference than ion chromatography,with high sensitivity,and low cost.h was a good match for the detection of bromate in flour products and quality control requirements.关键词
