摘　　要：目的探讨微波消解-电感耦合等离子体发射光谱法(ICP-OES)测定膨化食品中铝的可行性。方法样品经微波消解后,采用ICP-OES对膨化食品中铝进行测定。结果 ICP-OES法相对标准偏差(RSD)4.0%,线性相关系数0.999 9,回收率88.46%。结论 ICP-OES测定膨化食品中铝具有RSD小、线性相关系数好、准确度高、测定快速等优点,是测定膨化食品中铝的理想方法。Objective The discussion of the accessibility to measure the aluminium content in puffed food by inductively coupled plasma optical emission spectrometry （ ICP - OES） , microwave digestion. Methods Using ICP - OES to measure the aluminium content in puffed food after the microwave digestion. Results The RSD of the determination is 4. 0% , r2 = 0. 999 9, the recovery is 88. 4 6 % . Conclusion The result determined by ICP - OES gets a low RSD, high linearity, high precision, and simplicity, which implies it a ideal method for determination.
