Abstract

Eu and Am doped glasses were interacted with synthetic interstitial claywater (SIC) and corresponding reference leachant, humic acids freeinterstitial solution (IS) to investigate the influence of humic acids onthe leaching behaviour of the waste glass. Static leach tests were carriedout at 40°C and 90°C. The release of the lanthanide Eu and the actinide Amfrom the glass was obviously enhanced by the presence of humic acids. Theleaching of transition elements, Fe and Ti strongly depends on the humicacids concentration. The leaching of glass matrix components, Al and B wasalso influenced by the concentrations of humic acids. However, humic acidshave little effect on the leaching of glass matrix element Si.
