Reactive uptake coefficients for multiphase reactions determined by a dynamic chamber system
<p>Dynamic flow-through chambers are frequently used to measure gas exchange rates between the atmosphere and biosphere on the Earth's surface such as vegetation and soils. Here, we explore the performance of a dynamic chamber system in determining the uptake coefficient <span class=&q...

| description | <p>Dynamic flow-through chambers are frequently used to measure gas exchange
rates between the atmosphere and biosphere on the Earth's surface such as
vegetation and soils. Here, we explore the performance of a dynamic chamber
system in determining the uptake coefficient <span class="inline-formula"><i>γ</i></span> of exemplary gases
(O<span class="inline-formula"><sub>3</sub></span> and SO<span class="inline-formula"><sub>2</sub></span>) on bulk solid-phase samples. After characterization
of the dynamic chamber system, the derived <span class="inline-formula"><i>γ</i></span> is compared with that
determined from a coated-wall flow tube system. Our results show that the
dynamic chamber system and the flow tube method show a good agreement for
<span class="inline-formula"><i>γ</i></span>in the range of 10<span class="inline-formula"><sup>−8</sup></span> to 10<span class="inline-formula"><sup>−3</sup></span>. The dynamic chamber
technique can be used for liquid samples and real atmospheric aerosol
samples without complicated coating procedures, which complements the
existing techniques in atmospheric kinetic studies.</p> |
