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. |
