摘要
本文研究了用氢化物发生-原子吸收法测定食品容器等样品中的锑含量，样品用4％乙酸提取，采用氢化物发生-原子吸收法进行测定。本文实验利用添加法测定回收率，其平均回收率为95．0％-102．0％，本方法RSD小于5．3％，低检出限0．001mg·L-1。
Antimony in food container was studied by hydride generation-atomic absorption spectrometry method. Antimony was abstracted by 4% acetic acid and determined by atomic absorption spectrometry.The recovery rate was determined by additive process.The average recovery rate was 95.0%-102.0% and with RSD being 5.3%. The lowest detection limit was 0.001mg. L-1.
