Modeling cloud effects on hydrogen peroxide and methylhydroperoxide in the marine atmosphere
Cheol-Hee Kim,Sonia M. Kreidenweis,Graham Feingold,Gregory J. Frost,Gregory J. Frost,Michael Trainer +5 more
TL;DR: In this article, a coupled gas phase and aqueous phase chemical model representing a remote non-precipitating cloudy boundary layer was used to investigate the effect of cloud contact on the recovery of the H2O2/CH3OOH ratio.

Designing Wet Scrubbers for SO2 Absorption into Fairly Concentrated Sulfuric Acid Solutions Containing Hydrogen Peroxide
TL;DR: In this paper, the absorption rate of SO 2, diluted with nitrogen up to concentrations of 500 Pa, was performed at 20°C and 1 atm, with water and sulfuric acid solutions containing hydrogen peroxide in two different contactors: a packed column and a cable scrubber.

Numerical simulation of wet scavenging of air pollutants—II. Modeling of rain composition at the ground
TL;DR: In this article, the authors investigated the major scavenging mechanisms of most pollutants in convective showers appear to be similar to those in frontal precipitations, and they found that NH 4 and NO 3 are gas absorption, whereas the absorption of SO 2 by aqueous drops and the oxidation of S(IV) by H 2 O 2 and O 3 in the annealing phase are the major formation and scavenging mechanism for SO 4 ; the scavenging by raindrops in the below-cloud region is the dominant removal mechanism for coarse particles, whereas nucleation is the major

The importance of atmospheric ozone and hydrogen peroxide in oxidising sulphur dioxide in cloud and rainwater
TL;DR: In this paper, the authors used the experimental data to calculate the rate of sulphate formation in water droplets under atmospheric conditions for each of the three oxidants, i.e., ozone, ozone and hydrogen peroxide.

Mechanism of the homogeneous oxidation of sulfur dioxide in the troposphere
TL;DR: In this article, an evaluation of the existing kinetic data related to the elementary, homogeneous reactions of SO 2 within the troposphere is made, and a set of preferred values of the rate constants for these reactions is presented.

Kinetics of the oxidation of sulfite by hydrogen peroxide in acidic solution
M. R. Hoffmann,J. O. Edwards +1 more
TL;DR: In this article, the authors investigated the kinetics of sulfite by hydrogen peroxide over the pH range 4-8 and showed that the reaction probably proceeds via a nucleophilic displacement by H 2O_2 on HSO_3^- to form a peroxomonosulfurous acid intermediate which then undergoes a rate-determining rearrangement.
