| Abstract: | 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. |
