| Abstract: | Aim To determine aluminium in fried twisted flour dough. Methods Pretest samples using mixed acid, and Mg（NO3）2 were adopted as matrix modifier to determine aluminium by graphite furnace atomic absorption spectrometry. Results The detection limit was 4.8μg/L,relative standard deviation（RSD） was 0.952%-6.329%,Recovery rate was 88.8% -105.5%. Conclusion This method is suitable for determination of aluminium in flour food. |
