However, kinetic data about this reaction on authentic mineral dust are scarce and are mainly limited to low relative humidity (RH) conditions. In addition, little is known about the role of hydrogen peroxide (H&lt;/span&gt;&lt;sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: small;&quot;&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: medium;&quot;&gt;O&lt;/span&gt;&lt;sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: small;&quot;&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: medium;&quot;&gt;) in this reaction. Here, we investigated the uptake kinetics of SO&lt;/span&gt;&lt;sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: small;&quot;&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: medium;&quot;&gt; on three authentic mineral dusts (i.e., Asian mineral dust (AMD), Tengger desert dust (TDD), and Arizona test dust (ATD)) in the absence and presence of H&lt;/span&gt;&lt;sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: small;&quot;&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: medium;&quot;&gt;O&lt;/span&gt;&lt;sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: small;&quot;&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: medium;&quot;&gt; at different RHs using a filter-based flow reactor, and applied a parameter (effectiveness factor) to the estimation of the effective surface area of particles for the calculation of the corrected uptake coefficient (γ&lt;/span&gt;&lt;sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: small;&quot;&gt;c&lt;/span&gt;&lt;/sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: medium;&quot;&gt;). We found that with increasing RH, the γ&lt;/span&gt;&lt;sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: small;&quot;&gt;c&lt;/span&gt;&lt;/sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: medium;&quot;&gt; decreases on AMD particles, but increases on ATD and TDD particles. This discrepancy is probably due to the different mineralogy compositions and aging extents of&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

Furthermore, the presence of H&lt;/span&gt;&lt;sub&gt;&lt;span style=&quot;font-size: small;&quot;&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;/span&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: medium;&quot;&gt;O&lt;/span&gt;&lt;sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: small;&quot;&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: medium;&quot;&gt; can promote the uptake of SO&lt;/span&gt;&lt;sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: small;&quot;&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: medium;&quot;&gt; on mineral dust at different RHs. The probable explanations are that H&lt;/span&gt;&lt;sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: small;&quot;&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: medium;&quot;&gt;O&lt;/span&gt;&lt;sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: small;&quot;&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: medium;&quot;&gt; rapidly reacts with SO&lt;/span&gt;&lt;sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: small;&quot;&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: medium;&quot;&gt; on mineral dust in the presence of adsorbed water, and OH radicals, which can be produced from the heterogeneous decomposition of H&lt;/span&gt;&lt;sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: small;&quot;&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: medium;&quot;&gt;O&lt;/span&gt;&lt;sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: small;&quot;&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: medium;&quot;&gt; on the mineral dust, immediately react with adsorbed SO&lt;/span&gt;&lt;sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: small;&quot;&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;span style=&quot;color: rgb(0, 0, 0); font-size: medium;&quot;&gt; as well.
