<abstract>
<p>Peroxynitric acid uptake to ice and snow has been proposed to be a major
loss process from the atmosphere with impacts on the atmospheric oxidation
capacity. Here we present results from a laboratory study on the interaction
of peroxynitric acid with water ice at low concentration. Experiments were
performed in a coated wall flow tube at atmospheric pressure and in the
environmentally relevant temperature range of 230 K to 253 K. The
interaction was found to be fully reversible and decomposition was not
observed. Analysis based on the Langmuir adsorption model showed that the
partitioning of peroxynitric acid to ice is orders of magnitude lower than
of nitric acid and similar to nitrous acid partitioning behavior. The
partition coefficient (&lt;I&gt;K&lt;/I&gt;&lt;sub&gt;LinC&lt;/sub&gt;) and its temperature dependency can be
described by 3.74 Ã— 10&lt;sup&gt;&amp;minus;12&lt;/sup&gt; Ã— &lt;I&gt;e&lt;/I&gt;&lt;sup&gt;(7098/&lt;I&gt;T&lt;/I&gt;)&lt;/sup&gt; [cm].
Atmospheric implications are discussed and show that the uptake to cirrus
clouds or to snow-packs in polar areas is an important sink for peroxynitric
acid in the environment.</p>
