摘要
采用顺序注射进样氢化物发生原子荧光光谱法测定PET食品接触材料中痕量锑溶出量。研究硼氢化钠浓度、氢氧化钠浓度、介质酸度、载气流量及共存元素对测定的影响。锑的检出限为0.026μg/L;定量下限为0.086μg/L;回收率为94.7%～103.6%;相对标准偏差为0.46%～1.17%(n=8)。
A method for the determination of the trace release of Antimony from PET Food contact material by sequential injection-hydride generation atomic fluorescence spectrometry was developed.The infection of NaBH4 concentration,NaOH concentration, medium acidity, carrier gas flow and coexistence element were studied.The detection limit was 0.026 μg/L.The LOQ was 0.086 μg/L. The recovery was in the range of 94.7 %- 103.6 %.The RSD was 0.46 %-1.17 %（n=8）.
