| Abstract: | In this article,the condition of sulfhydryl cotton enriching and desorping the trace element Pb in wine was researched,and the absorbance value of its eluate was measured by Flame Atomic Absorption Spectrophotometer,the ratio of recovery was over90%.The relative standard deviation achieves about 4%.This method was quite suitable for food analysis,on-the-spot rapid detection of enrichment and so on for its simplicity,quickness,high-precision and high sensitivity. |
