摘要：

The TcO4− precipitation with organic complexes of Cu(II) from nitric acid solutions was studied. Complex Cu(phen)3(NO3)2 was chosen as the optimal precipitant. The conditions for maximum Tc precipitation of 95 ± 3 % were determined. It was shown the possibility to obtain metal-Tc alloys by thermal treatment of the precipitates. As found, the addition of the fusible metal (Sn) to the sediment was required to receive appropriate matrix. Cu–Tc–Sn matrix was tested for Tc leaching.
