摘要
通过优化实验程序,建立了微波消解-原子荧光光谱法测定食品中锑含量的方法.结果表明,锑在 0～10 μg·L-1 时线性关系良好,线性相关系数为 0.999 78,检出限为 0.03 μg·L-1,加标回收率为95.5%～103.5%,相对标准偏差为 0.2%～3.6%.该方法方便快捷,准确度好,精密度高,适用于饮料中锑含量的测定.
Abstract
By optimizing the experimental procedure,a method for the determination of antimony in food by microwave digestion-atomic fluorescence spectrometry was established.The results showed that the linear relationship of antimony was good in the range at 0 μg·L-1 to 10 μg·L-1,the linear correlation coefficient was 0.999 78,the detection limit was 0.03 μg·L-1,the recovery rate was 95.5%to 103.5%,and the relative standard deviation was 0.2%to 3.6%.The method is convenient,fast,accurate and precise,which is suitable for the determination of antimony content in beverages.
