Abstract
The photochemical aquation of K2 TcBr6 in 2M HRr, 1M HClO4 and 1M H2SO4 has been studied. The absorption spectra of the various Tc(IV) species were measured after the electrophoretic separation. The spectrophotometric changes and the yield of each species as a function of the UV irradiation time were determined. After 25 hours of irradiation of HBr and HClO4 solutions the main species were the cationic ones (∼80%) but in H2SO4 solution the neutral species reached a yield of 90%. The oxidation of Tc(IV) species to TcO −4 proceeded more rapidly and extensively in HClO4 than in HBr and H2SO4.
