Abstract
The rate of oxidation of SO2 by oxygen in "pure" water was found to vary with pH, having a maximum rate at pH 6 where the half life for the reaction was 300 ± 50 min. It is believed that the variable results for the oxidation in "pure" water were due to contamination by trace (about 5 × 10-8 M) Fe(III). It was shown that Fe(III) at 10-6 M concentration is a true catalyst for SO2 solution oxidation and that its role can be explained by a free radical chain reaction. Using the rate data obtained in these experiments a calculation of the possible rate of oxidation of SO2 in fog droplets in the atmosphere is described. © 1974.
