摘要
对市售的膨化食品、鲜、干水产品、豆制品采用微波仪消解，在电感耦合等离子体质谱仪上采用钪（Sc）作为内标元素对其中铝含量进行直接定量分析。方法前处理简便，测量快速、灵敏、准确。方法检出限为0．3mg／kg，相对标准偏差〈3％，加标回收率在85％-104％。
The determination of Aluminium in foods with microwave digestion - inductivly coupled plasma mass spectrometer （ ICP - MS） were introduced in this paper, using the scandium （Se） 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 %.
