Reactions between the SO4*(-) radical and some common anions in atmospheric aqueous droplets.
The rate constants of reactions between the SO4*(-) radical and some common anions in atmospheric aqueous droplets e.g. Cl-, NO3-, HSO3- and HCO3- were determined using the laser flash photolysis technique. Absorption spectra of SO4*(-) and the product radicals were also reported. The chloride ion was evaluated among all the anions to be the most efficient scavenger of SO4*(-). The results may supply useful information for a better understanding of the vigorous radical-initiated reactions in atmospheric aqueous droplets such as clouds, rains or fogs.
