The results of the content determination of the selected trace elements Ti, Sr, Ba, Zn, Pb, Cu, S, P, Cr, Cd, Ni, Zr, Mo, Rb, Sc, Y, and REEs were presented in this article. Studies were carried out to define the purity of limestones. The elements were measured in the carbonate minerals of Middle Triassic limestones of the Opole Silesia in Poland, using ICP-MS and X-ray fluorescence (XRF). Moreover, the contents of Sc and REY were also determined by electron microprobe analysis. These methods are characterized by high accuracy and precision of the measurement. The research results show that the contents of trace elements vary from below 1 ppm up to some hundreds ppm. The highest content was measured for strontium and the lowest for barium, elements characteristic of aragonite. Their occurrence indicates the presence of aragonite in the primary carbonate material. Some trace elements form substitutions in clay or carbonate minerals. Zn, Pb, Cu, Mo, and Ni may be associated with sulfides, and Ti and Cr may be associated with oxides. Sc and REY usually substitute Ca ions in calcite. The contents of measured Ce, Nd, Sm, Dy, Er, and Y vary from below 1 ppm up to 6 ppm, and Sc from 0 ppm to 10 ppm.
本文展示了所选微量元素钛(Ti)、锶(Sr)、钡(Ba)、锌(Zn)、铅(Pb)、铜(Cu)、硫(S)、磷(P)、铬(Cr)、镉(Cd)、镍(Ni)、锆(Zr)、钼(Mo)、铷(Rb)、钪(Sc)、钇(Y)和稀土元素(REEs)的含量测定结果。开展了研究以确定石灰石的纯度。使用电感耦合等离子体质谱法(ICP-MS)和X射线荧光光谱法(XRF)对波兰奥波莱西里西亚地区中三叠世石灰石的碳酸盐矿物中的这些元素进行了测量。此外,钪(Sc)和稀土元素钇(REY)的含量也通过电子微探针分析进行了测定。这些方法具有测量精度高和准确度高的特点。研究结果表明,微量元素的含量从低于1 ppm到数百ppm不等。测量到的锶含量最高,钡含量最低,这两种元素是文石的特征元素。它们的存在表明原生碳酸盐物质中存在文石。一些微量元素在粘土或碳酸盐矿物中形成替代物。锌(Zn)、铅(Pb)、铜(Cu)、钼(Mo)和镍(Ni)可能与硫化物有关,而钛(Ti)和铬(Cr)可能与氧化物有关。钪(Sc)和稀土元素钇(REY)通常在方解石中替代钙离子。所测铈(Ce)、钕(Nd)、钐(Sm)、镝(Dy)、铒(Er)和钇(Y)的含量从低于1 ppm到6 ppm不等,钪(Sc)的含量从0 ppm到10 ppm不等。
