摘要
目的研究测汞仪固体直接进样方法测定保健食品中总汞,通过与国标方法比较验证结果的可靠性。方法采用测汞仪固体直接进样和原子荧光光谱法两种方法对保健食品中的总汞进行测定。结果几种不同浓度加标的保健食品测汞仪测定的总汞结果与原子荧光法测定结果相符,回收率在88%～116%之间,RSD<10%。结论测汞仪直接固体进样测定保健食品中总汞的方法具有准确、快捷、运行成本低、无环境污染等优点,和现有国标原子荧光法测定同一样品,测定结果具有可比性,方法具有可推广性。
Objective To validate the mercury analyzer direct solid sampling method for determination of total mercury in health food. Methods Mercury analyzer direct solid sampling and atomic fluorescence spectrometry were used for determination of total mercury in health food. Results The results were consistent between the two methods in health food spiked with different concentrations of mercury. The recovery was 88%- 116% with RSD 〈 10%. Conclusion Determination total mercury by mercury analyzer direct solid sampling method in health food was accurate, fast, low cost and without pollution. The method was comparable to the national standard method and could be applied nationwide.
