摘要

摘要评估了蒸馏水中黄铁矿 FenSn+1 (I) 和锡黄铁矿 Sb2S3 (II) 对过硫酸盐的吸附情况。发现其分布系数分别为 185 和 223 cm3/g。对从过硫酸钾（KTcO4）水溶液中黄铁矿和闪长岩表面吸收的 99Tc 的化学态进行了 XPS 研究。研究发现，锝（IV）离子主要存在于所研究样品的表面，黄铁矿表面的锝离子浓度是闪长岩表面的 5.7 倍。在黄铁矿表面观察到 13% 的掺杂锝（VII）离子。

XPS Determination of the Oxidation State of 99Тс Isotope Absorbed on the Surface of Pyrrhotite FenSn+1 and Stibnite Sb2S3

Sorption of pertechnetate on pyrrhotite Fe_nS_n+1 (I) and stibnite Sb₂S₃ (II) from distilled water was evaluated. The distribution coefficients were found to be 185 and 223 cm³/g, respectively. The XPS study of the chemical state of ^99Tc absorbed on the surface of pyrrhotite and stibnite from aqueous solution of potassium pertechnetate (KTcO₄) was carried out. It was found that Tc(IV) ions are present mostly on the surface of the studied samples, their concentration was 5.7 times higher on the surface of pyrrhotite compared to that on the surface of stibnite. A 13% admixture of Tc(VII) ions on the surface of pyrrhotite was observed.
