On Iron Enrichment on Nuclear Waste Glass During Leaching

Static leach tests were carried out on a nuclear waste glass (SRL-165) at two different SA/V-ratios of 0.85cm-1 and 0.079cm-1 at 90°C. Fourier transform infra-red reflection spectroscopy revealed that Fe tended to precipitate on the surface of the glass when leached at 0.079cm-1, 90°C for more than...

Summary:Static leach tests were carried out on a nuclear waste glass (SRL-165) at two different SA/V-ratios of 0.85cm-1 and 0.079cm-1 at 90°C. Fourier transform infra-red reflection spectroscopy revealed that Fe tended to precipitate on the surface of the glass when leached at 0.079cm-1, 90°C for more than 14 days. X-ray photoelectron spectroscopy indicated that Fe which precipitated on the specimen surface was a mixture of Fe2+ and Fe3+; the ratio of Fe2+/Fe3+ would be determined by the redox conditions of surrounding water.
