    1NAA OF ARCHAEOLOGICAL REFERENCE SAMPLE ANCINT CERAMIC KPS-1

    • 摘要: 按比例选取宋、元、明三个朝代具有代表性的瓷器碎片,制成标准样。利用仪器中子活化分析的相对法和K_0法测定了这个样品中24种元素(Sm,Ce,Lu,Yb,Nd,La,Tb,Eu,U,Th,Hf,As,Cs,Sb,Sc,Rb,Cr,Zn,Ta,Co,Ba,Fe,Na,K)的含量。同时平行的测定了国际标准参考物SRM1632a,BCR_(-1),GXR_(-4)和JG_(-1)。这些国际标准参考物的测定值与文献值是一致的。

       

      Abstract: A typical pottery sample has been prepared by mixing unearthed potshards from Song, Yuan and Ming dynasties in certain proportion. The potshards sample are cleaned, dried, ground and sieved, and 200 mesh powder is selected. The powdered sample is dried again before being sealed in polyethylene bottles, The sample is analysed for 24 elements(Sm, Ce, Lu, Yb, Nd, La, Tb, Eu, U, Th, Hf, As, Cs, Sb, Sc, Rb, Cr, Zn, Ta, Co, Ba, Fe,Na and K by INAA and K0 method. As a control for accuracy, standard reference materials SRM 1632a, BCR-1, GXR-4 and JG-1 are analysed. The agreement between our results and literature values is satisfactory.
