摘要

由于氧化钌的挥发性，在玻璃化过程中用于固定核废料的硼硅玻璃中的钌含量并不确定。这项研究开发了一种定量方法，利用电感耦合等离子体质谱法（ICP-MS）测定含有核废料示踪核素的硼硅玻璃中的钌含量。研究结果表明，硼硅玻璃中的钌在 350 °C 下 8 小时可被 NaOH 完全分解，回收率不低于 95%，检出限为 0.4 mg kg-1。该方法已成功应用于实际样品的测定。

Determination of ruthenium in borosilicate glasses by inductively coupled plasma mass spectrometry

Ruthenium quantities in borosilicate glasses, used in vitrification process to nuclear waste immobilization, is uncertain due to the volatility of ruthenium oxide. In this work, a quantitative method was developed to determinate the content of ruthenium in the borosilicate glasses containing nuclear waste tracer nuclides by inductively coupled plasma mass spectrometry (ICP-MS). The research showed that the ruthenium in borosilicate glasses can be completely decomposed by NaOH at 350 °C for 8 h. A recovery of no less than 95% and a detection limit of 0.4 mg kg⁻¹ were obtained. The method has been successfully applied for the determination of actual samples.
