Abstract |
This is the final report on a three year project to study the kinetics and mechanisms of some 105 reactions involving the aqueous oxidation of sulfur dioxide and nitrogen oxides in mixed catalyst-oxidant systems at low pH (0-3). The 105 systems involve six redox reaction types: SO2/O2; SO2/NOx; SO2/H2O2; SO2/O3; NOx/O3; NOx/H2O2. Mn(+2) and Fe(+2) are the only important metal catalysts. In the SO2/NOx system the reaction is rapid producing N2O. The SO2/H2O2 is extremely rapid and could account for the rapid formation of sulfate in the atmosphere when significant amounts of aerosol are present. The SO2/O3 reaction is not as rapid as the peroxide but the relative concentrations of the two makes the ozone reaction also significant. |
