[Determination of trace sulfur and mercury in the Chinese traditional medicine].
This paper reports that the sulfur compounds of traditional Chinese medicine were reduced to S2- by Auger reagent, and determined by cold atomic fluorescence. At the same time the trace mercury was determined. The conditions the for quantitative determination of Hg2+ and S2- were obtained. The linear range of the determination is 11.20-55.60 mg.mL-1, the correlation coefficient is 0.999 78. In this method, little reagent is needed, the treatment of the sample is simple, the process of determination is convenient, and the sensitivity is high.
