摘要
采用原子荧光法(AFS)和全谱直读电感耦合等离子体发射光谱法(ICP-OES)检测了食品包装材料中微量锑。用4%乙酸溶液,在60℃条件下浸泡0.5 h,测定浸泡液中锑的质量浓度。结果表明,两种方法相比,AFS法比ICP-OES法的检出限低,有精密度、灵敏度、稳定性高,回收率好等优点,是检测微量锑的理想方法。
Trace amounts (AFS) and optical direct of antimony in food packaging materials by atomic fluorescence spectrometry reader - emission spectroscopy (ICP - OES) method, with 4% acetic, at the temperature of 60 ~C for 0. 5 h, access to soak an accurate determination of the heavy metal antimony concentration. The result shows that compared to the two method, the AFS method has the better detection of limiting, precision, sensitivity, stability and recovery which is the ideal way for detection trace amounts of antimony.
