Abstract

[99Tc(III) (acac)3] was synthesized by published procedure, but recovered by extraction into CH2Cl2. The product was purified by preparative HPLC over a reversed phase column, RP18, using a mobile phase of 1∶1 CH3OH∶H2O. The cationic complex [99Tc(IV) (acac)3]+ prepared by the oxidation of the purified neutral Tc(III) complex was unstable in methanol/methanol-water medium, being reduced back to the Tc(III) complex.
