目的:建立一种原子荧光光谱法同时测定罐装食品中锡的方法。方法:采用HNO3∶H2SO4处理食品样品,优化测定条件,氢化物发生—原子荧光光谱法测定罐装食品中锡。结果:锡的检出限、相对标准偏差、回收率分别为:0.046μg/L,3.27%,96.33%~99.54%。结论:方法灵敏度高,准确、快捷,测定罐装食品锡,省时,省力。 Objective: To establish a method for simultaneous determination of tin in canned foods by atomic fluorescence spectrometry. Methods: The food samples were treated with HNO3:H2SO4, and the determination conditions were optimized. The determination of tin in canned food by hydride generation-atomic fluorescence spectrometry. Results: The detection limits, relative standard deviations and recoveries of tin were 0.046μg / L, 3.27% and 96.33% ~ 99.54%, respectively. Conclusion: The method has high sensitivity, accuracy and quickness. The determination of canned tin, saving time and effort.
