In recent years, the study on palaeodiet is an important research in the international archaeological field. Trace elements in human bones can supply a lot of valuable information to reconstruct ancient diet. In this study, The trace elements in Bronze age Cheshi human costa from Chubeixi cemetery in shanshan, Xinjiang were determined by ICP-AES. The sample was dissolved by HNO3 and HCl. Under the optimum conditions, eight elements can be determined simultaneously. The recoveries of the method are in the range of 87.4%-106.6%, and RSDs are in the range of 0.5%-3.3%. The method is simple, rapid, precise and convenient to operate. The results would be helpful for research in archaeology. This analysis established Xinjiang' s consult system of trace elements analysis for ancient human bones. The effects of various concentrations of acid solution on analysis results, the interference of coexistent elements, standard addition recovery, and precision of the method were investigated.
近年来，古饮食研究是国际考古领域的一项重要研究。人类骨骼中的微量元素能够为重建古代饮食提供许多有价值的信息。在本研究中，采用电感耦合等离子体发射光谱法（ICP - AES）测定了新疆鄯善洋海墓地青铜时代车师人肋骨中的微量元素。样品用硝酸和盐酸溶解。在最佳条件下，可同时测定8种元素。该方法的回收率在87.4% - 106.6%之间，相对标准偏差在0.5% - 3.3%之间。该方法操作简单、快速、准确、方便。研究结果将有助于考古学研究。本分析建立了新疆古代人类骨骼微量元素分析的参考体系。考察了不同浓度酸溶液对分析结果的影响、共存元素的干扰、标准加入回收率及方法的精密度。
