The rate constants for reactions of the SO 4 − radical anion with some low molecular weight monocarboxylic acids (MCAs) and dicarboxylic acids (DCAs) and their anions using the laser flash photolysis-long path laser absorption (LFP-LPLA) technique

The influence of some low weight mono- and di-carboxylic acids, which were selected on the basis of analysis of the water-soluble fraction of size segregated marine and urban aerosols collected in Slovenia, on the kinetics of S(IV) oxidation catalyze

In the presence of hygroscopic material, stable aqueous droplets form at relative humidity below 100%. In this work, we examined the role and importance of NH 3 in SO 2 oxidation under haze conditions. Synthetic deposits composed mainly of NaCl and N

The reaction kinetics of S(IV) autoxidation catalyzed by Mn(II) in the pH range 3–5 typical for atmospheric liquid water, was investigated. For reactions with pH maintained constant during the reaction course, the predictions obtained by a simple i

Particles and droplets containing liquid water represent very important media for chemical reactions. The presented investigation was focused on the formation of acidic product (sulfate) during SO2 oxidation in the presence of manganese under haze co

We studied the influence of ionic strength as well as type of supporting electrolyte on the rate of oxidation of dissolved SO2 catalyzed by Mn(II) under dark conditions at pH 3. Two electrolytes were chosen; NaCl and NaNO3. NaCl is an important compo

For the first time, continuous aerosol measurements were performed in the Škocjan Caves, one of the most important cave systems in the world, and listed by UNESCO as a natural and cultural world heritage site since 1986. Measurements of PM10 were pe

During two campaigns in winter 2004, size segregated impactor samples (0.1-10 microm) and filter samples were taken in two Central European cities (Vienna, Austria and Ljubljana, Slovenia). The impactor samples were analyzed for major inorganic ions

The chemical composition as well as the water uptake characteristics of aerosols was determined in size-segregated samples collected during November 2002 on the Slovenian coast. Major ions, water-soluble organic compounds (WSOC), short-chain carboxyl

The reaction products (i.e., sulfate (SO42−) and dithionate (S2O62−)) of S(IV) oxidation in the presence of iron(III) under different experimental conditions were investigated. Ion-interaction chromatography was used for the separation of sulfate
