Reactions between the SO4 center dot- radical and some common anions in atmospheric aqueous droplets

Abstract

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.-
