Therefore, it is known that iron artifact includes a small amount of charcoal. In this study, a wet method of carbon extraction from iron artifacts was developed. This new method consists of dissolution of iron with Cu^<2+> ion, dissolution of cupper with HCl and collection of charcoal powder on quartz wool as coagulated colloid particles. It was shown that this wet method has a high extraction yield (80-90%) and low contamination of charcoal from modern carbon. This method has the ability to collect charcoal from a sample of low carbon concentration when the sample is treated in the larger reactor., タンデトロン加速器質量分析計業績報告 Summaries of Researches Using AMS 1996 (平成8)年度}, pages = {258--266}, title = {<14>^C年代測定用鉄試料からの湿式炭素抽出法}, volume = {8}, year = {1997} }
