For many years, the interaction between dust particles and water molecules has been a subject of interest for atmospheric sciences community. However, influence particle size on hygroscopicity mineral is poorly evaluated. In current study, diffused reflectance infrared Fourier transform (DRIFT) spectroscopy used to evaluate in situ adsorption natural Arizona test (ATD) particles. Five different ATD fractions, 0–3, 5–10, 10–20, 20–40, 40–80 μm, are used, corresponding entire range uplifted...
The adsorption of isopropanol on Gobi dust was investigated in the temperature (T) and relative humidity (RH) ranges 273-348 K <0.01-70%, respectively, using zero air as bath gas. kinetic measurements were performed a novel experimental setup combining Fourier-Transform InfraRed spectroscopy (FTIR) selected-ion flow-tube mass spectrometry (SIFT-MS) for gas-phase monitoring. initial uptake coefficient, γ0, measured function several parameters (concentration, temperature, humidity, mass). γ0...
Mineral dust is a major component of atmospheric aerosol that can impact both the climate and oxidative capacity atmosphere. It has been recently suggested heterogeneous processes on natural mineral dusts act as sink volatile organic compounds (VOCs) possibly sources oxygenated (OVOCs). More precisely, literature findings suggest such isoprene (ISP), highest emitted biogenic compound (BVOC) in atmosphere, could be involved particles account for OVOC formation. Hence, within this framework,...
The adsorption properties of mineral dust toward organic molecules are poorly characterized so far. Heterogeneous processes between trace gases and particles can affect the oxidative capacity atmosphere as well constitute additional sources or sinks for these species. current study investigates efficiencies natural samples collected from North West Africa, Saudi Arabia, Arizona desert regions isopropyl alcohol (IPA), a common pollutant released in significant amounts atmosphere, which is...
The heterogeneous interaction of isoprene with TiO2 surfaces was studied under dark and UV light irradiation conditions. experiments were conducted at room temperature, using zero air as bath gas, in a flow reactor coupled SIFT-MS (selected-ion flow-tube mass spectrometer) FTIR spectrometer for the gas-phase monitoring reactants products. steady-state uptake coefficient yields products formed measured function (9–120 mg), intensity (37–112 W m−2), concentration (36–12000 ppb), relative...
