Abstract
Tc(IV) is oxidized with persulfate ions in HClO{sub 4} solution by reactions with both S{sub 2}O{sub 8}{sup -2} ion and product of its thermal decomposition, Caro acid, H{sub 2}SO{sub 5}. The reaction rate at 35 deg C and solution ionic strength {mu} = 1 is described by the equation -d[Tc(IV)]/dt = k{sub 1}[Tc(IV)][S{sub 2}O{sub 8}{sup 2-}] + k{sub 3}[Tc(IV)][HSO{sub 5}{sup -}]/[H{sup +}], where k{sub 1} = 0.88 {+-} 0.04 l mol{sup -1} min{sup -1} and k{sub 3} = 110 {+-} 5 min{sup -1}. With increasing ionic strength to {mu} = 2, both rate constants decrease (k{sub 1} = 0.58 + 0.08 l mol{sup -1} min{sup -1} and k{sub 3} = 52 {+-} 2 min{sup -1} at 35 deg C). The activation energy of the overall reaction is 77.7 {+-} 8.1 kJ mol{sup -1}. The mechanisms of both reactions are discussed.
