Abstract:A rapid and sensitive method was established for the determination of aluminum in food.Purple wheat,vigna minima and the fried dough sticks was elected as samples,after wet digestion,the samples were determined by double-standard sandwich method and standard curve method.The results showed that there was a linear relationship between trivalent aluminium and fluorescence intensity as trivalent aluminum mass concentration within the range of 0.10~50 μg/mL-1,the correlation coefficient r=0.9990,the recovery rate was 96.0%~107.2% and relative standard deviation RSD<1%(n=11).The method is rapid,simple,cheap with a small amount of sample,doesn't need drawing the standard curve and determining blank simple,which provides a new analysis technique for the determination of aluminum in food and is worth being spread.
