| description | The heterogeneous reaction of N<sub>2</sub>O<sub>5</sub> with airborne illite and
Arizona test dust (ATD) particles was investigated at room temperature and
at different relative humidities using an atmospheric pressure aerosol flow
tube. N<sub>2</sub>O<sub>5</sub> at concentrations in the range 8 to
24 × 10<sup>12</sup> molecule cm<sup>−3</sup> was monitored using thermal-dissociation
cavity ring-down spectroscopy at 662 nm. At zero relative humidity a large
uptake coefficient of N<sub>2</sub>O<sub>5</sub> to illite was obtained, γ(N<sub>2</sub>O<sub>5</sub>)
= 0.09, which decreased to 0.04 as relative humidity was increased to
67%. In contrast, the uptake coefficient derived for ATD is much lower
(~0.006) and displays a weaker (if any) dependence on
relative humidity (0–67%). Potential explanations are given for the
significant differences between the uptake behaviour for ATD and illite and
the results are compared with uptake coefficients for N<sub>2</sub>O<sub>5</sub> on
other mineral surfaces. |
