| Abstract: | The determination of Aluminium in foods with microwave digestion-inductivly coupled plasma mass spectrometer(ICP-MS) were introduced in this paper,using the scandium(Sc) as internal standard.This method was simple,rapid,sensitive and accurate.The determination limit was 0.3 mg/kg,the recovery rate of standand addition was 85 %~104 % and the relative standard deviation was less than 3 %. |
