Abstract

[Objective]To establish the method of determining arsenic in health products by graphite furnace atomic absorption spectrometry.[Methods]The health products was digested by microwave digestion,determination of arsenic by graphite furnace atomic absorption spectrometry.[Results]Linear regression equation was Y=0.0013 X+0.00074,r=0.9999,the detection limit was 0.13 μg/L,the recovery rate ranged from 93.1% ～ 96.5% and RSD ranged from 1.27% to 3.04%.[Conclusion]Graphite furnace atomic absorption spectrometry can be used for determination of arsenic in health products
