| High-level waste in at least two tanks at the Department of Energy’s Hanford site is an alkaline salt containing organic complexants, high strontium-90 activity, and transuranic species. A precipitation-filtration treatment process is being developed to separate the waste into high and low level streams. Iron and manganese solids forming after the filtration step of the treatment process may interfere with a subsequent ion exchange process. This project involves characterizing the available complexes of iron and manganese formed with the parent complexing agents in the filtrates as well as their fragmented products. The scope of this project includes the development of new analytical methods for qualitative and quantitative assessments of the complexants with reliable and sensitive results. Ion chromatography and high performance liquid chromatography methods were developed thus far, and this poster will review the results to date. |
