| Abstract: | By using the digesting system of nitric acid and hydrogen peroxide solution,impurity elements of Pb,Mn and Cr in food additive brilliant blue were determined by inductively coupled plasma atomic emission spectrometry（ICP-AES）.The detection limit of the method is 0.0050.015 μg/mL,and the recycling rate is in the range 95.30%～103.9%,and the RSD（%） is less than 3.05%.This method is convenient,quick and accurate.It can be used in determination of impurity elements in food additive brilliant blue. |
