摘　　要：采用压片制样波长色散X射线荧光光谱法对古陶瓷胎釉样品的Na2O、MgO、Al2O3、SiO2、P2O5、K2O、CaO、Sc、TiO2、V2O5、Cr2O3、MnO、Fe2O3、CoO、NiO、CuO、ZnO、Ga、As、Br、Rb、Sr、Y、Zr、Nb、Sn、Sb、Cs、BaO、La、Ce、Nd、Sm、Hf、PbO、Bi和Th等37个主、次、痕量组分进行测定。使用经验系数法和康普顿散射、背景作内标校正基体效应。方法经土壤和水系沉积物国家标准物质验证,测定值与标准值吻合;除个别组分,大多数元素11次测定的相对标准偏差(RSD)小于10%。方法的检出限、精密度和准确度能满足古陶瓷样品的分析要求,应用于7个古陶瓷样品的分析检测,分析结果与其他分析方法对比具有很好的一致性。A method for the determination of Na2O,MgO,Al2O3,SiO2,P2O5,K2O,CaO,Sc,TiO2,V2O5,Cr2O3,MnO,Fe2O3,CoO,NiO,CuO,ZnO,Ga,As,Br,Rb,Sr,Y,Zr,Nb,Sn,Sb,Cs,BaO,La,Ce,Nd,Sm,Hf,PbO,Bi and Th in pressed power pellets of ancient ceramics body and glaze by X ray fluorescence spectrometry was reported in this paper.The matrix effect was corrected by experience coefficients,Compton scattering and background as internal standard for trace elements determination.The method has been verified by analyzing the national standard Reference Materials of topsoil and stream sediment and the analytical results were in agreement with the certified values,and RSD（n=11） of most elements（except four elements） are less than 10%,indicating that our method has a high accuracy and can greatly satisfy ancient ceramics research work.The method has been applied to the determination of seven ancient ceramics samples.The obtained results were consistent with the results of other analysis methods.
