Abstract
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.
