| Abstract: | Objective ] A method for determination of arsenic（ As）, mercury（Hg） in ginseng seal pills by microwave digestion - hydride gen- eration atomic florescence spectrophotometry was established. Method] The samples were microwave digested by nitric acid, and were detec- ted by hydride generation atomic florescence speetrophotometry. Result] The recovery rate of As, Hg was 96.2% - 109.5% , 95.6% - 109.1% , RSD was less 5%. Conclusion] The method is rapid, accurate and reliable, which can meet the requirements for determination of As and Hg in ginseng seal pills. |
