Interaction of N2O5 with mineral dust

The heterogeneous chemical kinetics of N2O5 on CaCO3 and other atmospheric mineral dust surrogates

Uptake experiments of N2O5 on several mineral dust powder samples were carried out under continuous molecular flow conditions at 298±2 K. At [N2O5]0=(4.0±1.0)×10 cm−3 we have found γ ss values ranging from (3.5±1.1)×10−2 for CaCO3 to (0.20±0.05) for Saharan Dust with γss decreasing as [N2O5]0 increased. The uptake coefficients reported in this work are to be regarded as upper limiting values ow...
