摘要
目的：建立检测面制品中铝含量的电感耦合等离子体发射光谱方法.方法：样品经湿式消解后,用电感耦合等离子体发射光谱法对面制食品中铝进行测定.结果：方法最低检出限为0.016 mg/L,最低检出浓度0.16 mg/kg;在0.08～50 mg/L范围内呈线性关系,相关系数r=0.9999,回收率在94%～107%之间;测定结果相对标准偏差为0.60%～2.8%.结论：本方法操作简便、快速、准确、干扰小、检出限低、线性范围广,适用于面制食品中铝的测定.
Objective：To set up the analysis methods of aluminum in food of flour. Methods：Samples were acid clearing up and analyzed by inductively coupled plasma - atomic emission spectrometry （ ICP - AES）. Results： The recovery rate, relative standard deviation and detection limit were 94% - 107%, 0. 60% - 2. 8% and 0. 16 mg/kg, respectively. The linear range of the method was 0. 08 - 50 mg/L with a correlation coefficient of 0. 9999. Conclusion：The method is simple, rapid, accurate and suitable for determination aluminum in food of flour.
