摘要
目的建立保健食品蜂胶中总砷的分析方法。方法采用微波消解法对蜂胶样品进行前处理,氢化物发生-原子荧光法进行测定。结果测定总砷的线性范围为0-90μg/L,相关系数为0.999 5,方法回收率为96.6%-101.7%,RSD为1.08%。结论实验表明,本法准确灵敏,简便高效,适用于蜂胶中总砷的测定。
Objective This paper established the analysis method of total arsenic in propolis health food. Methods The propolis samples were pretreated by microwave digestion, hydride generation-Atomic Fluorescence Spectrometry deter-mination. Results The linear range for determination of total arsenic in this paper is 0, the correlation coefficient is 0.999 5, recovery rate of 96.6-101.7%, RSD 1.08%. Conclusions Experiments show that this method is accurate, sensitive, simple and efficient, suitable for determination of total arsenic in propolis.
