| Abstract: | The method is investigated to measure the aluminum in the flour products.With dry ashing the samples,aluminum is determined by graphite furnace atomic absorption spectrometry.The results show that the linear range is between 20 and 50 μg/L with R=0.999 8,RSD of 1.46% to 3.32%,and recovery rate of 96.4% to 98.5%.The limit of determination is 7.35 μg/L and the minimum detectable concentration is 3.50 μg/L.The results are consistent with the present national standard.This method is a quick and convenient technology for the measurement of aluminum in flour products. |
