Autor: Klaus J. Wannowius, Uwe Götz, Horst Elias

Publikováno v: Atmospheric Environment. 28:439-448

Stopped-flow spectrophotometry was used to study the oxidation of S(IV) by peroxomonosulfuric acid anion, HOOSO3− (=PMS), at 285 K in the pH range 0–12.5 in buffered aqueous solution under pseudo-first-order conditions (I = 1.0 M, Na2SO4). The re

Sulfur(IV) oxidation by hydrogen peroxide in aqueous suspensions of SiO2, Al2O3, TiO2 and zeolite

Autor: Horst Elias, Harald Hoβ, Klaus J. Wannowius

Publikováno v: Atmospheric Environment. Part A. General Topics. 25:1715-1717

Normal and stopped-flow spectrophotometry were used to study the rate of oxidation of sulfur(IV) (SO32−/HSO3−) by H2O2 in aqueous suspensions of finely divided SiO2, Al2O3, TiO2 and Na-A-zeolite buffered at pH 8.2 and 4.0. Within the limits of er
