Indirect Determination of Inorganic Sulfur in Traditional Chinese Medicine by Cold Atomic Fluorometry

采用冷原子荧光法间接测定中药材 (黄芪和使君子 )中的无机硫 ,建立了测定中药材中无机硫的方法 ,确定了定量分析的条件 .测定线性范围为 1 1 .1 2 ng/ ml～ 5 5 .60 ng/ ml,回归系数 r=0 .99978.该方法所需试剂较少、样品处理简单、测定灵敏度较高 。

Indirectly determine the inorganic sulfur in the traditional Chinese medicine by the cold atomic fluorometry, establish the method determining inorganic sulfur, and make the condition for quantitative analysis. The linear range of the determination is 11.20~55.60mg/ml, the correlation coefficient is 0.999 78. As for this method, the little reagent is needed, the treatment of the sample is simple, the process of determination is convenient, and the sensitivity is high.
