| Abstract: | The extraction of reduced99mTc with 5,7-dichloroxine, tributyl phosphate (TBP) and 1-phenyl-3-methyl-4-benzoyl-pyrazolone-5 (PMBP) from HCl−LiCl mixtures
has been studied. A mechanism of extraction is proposed and the stability of the chlorocomplexes of technetium (V) in a hydrochloric
and—lithium chlorid—perchloric acid mixture has been established using extraction data of99mTc and spectrophotometric measurements with99Tc. |
