Summary

Extraction of uranium from tissue matrix was studied using supercritical carbon dioxide containing modifier solvent. The extraction efficiency was investigated with carbon dioxide containing methanol, tri-n-octyl phosphine oxide (TOPO) in methanol and tri-n-butyl phosphate (TBP) in methanol as modifiers. The extraction behaviour of the UO2(NO3)2 · 2TOPO complex loaded on tissue was also investigated. Supercritical carbon dioxide modified with methanol alone was found to extract a maximum of about 76% uranium from tissue matrix.
