Reactivity of Hydroperoxyl/Superoxide Radicals in Aqueous Solution
One-electron reduction of oxygen produces the superoxide radical which is
associated with damage to biological systems.
Kinetic data for the superoxide radical and its protonated form, hydroperoxyl
radical (pKa = 4.8), in aqueous solution have been critically assessed.
Rate constants for more than 300 reactions with organic and
inorganic ions, molecules and other transient species have been tabulated.
Recent data have been compiled and evaluated and added, along with these data,
to the NDRL/NIST Solution Kinetics Database.
