出土青铜酒器残留物分析的尝试

Try On Analysis Remains of Unearthed Bronze Drinking Vessel

利用快速溶剂萃取法,从出土青铜酒器内的土壤中提取有机残留物,对其作高效液相色谱定性分析,发现其中含有酒石酸,表明这些青铜酒器在下葬时可能盛着酒。快速溶剂萃取法的萃取剂为1%磷酸(体积比)溶液,较之传统有机溶剂,操作时更为方便和安全。此方法可推广于陶器中残留物的分析,具有较为广泛的应用前景。

In this article, accelerated solvent extraction method was used to do residue extraction for the soil samples of unearthed bronze vessels, and HPLC analysis was used to do qualitative analysis, which has detected tartaric acid. This fact may suggest that they might contain fermented beverage when burying. The solvent was 1% （vol） phosphoric acid, which is more safe and envlronment-frlendly than traditional organic solvents. This method could be extended to the pottery soil residue analysis.
