【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。更多还原

【Abstract】 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.更多还原
