| 中文摘要 | the mercury in tibetan medicine has become important focus in the research on medicine safety evaluation. the total mercury and the ionic mercury in artificial gastric juice of tibetan medicine dangzuo were detected by gold amalgam enrichment-atomic fluorescence spectrometry (gae-afs). in the present study, tibetan medicine dangzuo was prepared by h(2)so(4)-kno(3) digestion system and artificial gastric juice. the established method and condition of instrument were investigated. under the optimum experimental conditions and instrumental operation parameters, the recovery(n=6)of hgs is 99.56% (rsd =1.94%), the limit of detection for mercury is 0.2 ng . l(-1), the linear range is 0 similar to 500 ng . l(-1),and r=0.999 9. then, the total mercury and the ionic mercury in artificial gastric juice in dangzuo samples from different tibetan regions were assayed. the result showed that the ranges of total mercury and ionic mercury in artificial gastric juice were 3.998 0 similar to 16.735 8 mg . g(-1) and 45.537 7 similar to 1 033.985 0 ng . g(-1), respectively. the analytical method mentioned above is rapid and accurate for determining the amount of mercury in tibetan medicine dangzuo. |
