The kinetics of uptake of gaseous HNO3 on thin films and crystallite grains of NaCl has been studied in a
coated wall tubular flow reactor coupled to a quadrupole mass spectrometer. A rapid gas-solid reaction
occurs with release of gaseous HCl. Uptake coefficients were measured at room temperature with a range of
partial pressures of HNO3 and H2O in the flow tube. ç values decreased with increasing HNO3 concentration
(4 1011 to 700 1011 molecule cm-3) and increased with H2O over the range 2 10-4 to 10 mbar. The
results were interpreted in terms of a mechanism of the reaction HNO3(g) + NaCl(s) f HCl(g) + NaNO3(s),
which involves ionization of adsorbed HNO3 molecules aided by surface-adsorbed water followed by reaction
of H3O+ with Cl- and desorption of product HCl molecules. The results allow estimation of the reactive
uptake coefficient for HNO3 on sea salt aerosol under atmospheric conditions.It consists of a Pyrex tubular reactor mounted
vertically below a differentially pumped molecular-beamsamp领
quadrupole mass spectrometer (Hiden HAL RGA301)
