  <dc:description>&lt;p&gt;&lt;span&gt;Solutions of 30% H&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;O&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;ranging from&amp;nbsp;&lt;/span&gt;&lt;i&gt;pH&lt;/i&gt;&lt;span&gt;&amp;nbsp;= 0 to&amp;nbsp;&lt;/span&gt;&lt;i&gt;pH&lt;/i&gt;&lt;span&gt;&amp;nbsp;= 11.5 have been used to oxidize anthracite at room temperature. The inorganic impurities, primarily pyrite, catalysed the oxidation and reduction of H&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;O&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;(the Fenton reaction) to form the hydroxyl radical; the oxidation of the organic matter was minimal and was observed only in strong acidic solutions (&lt;/span&gt;&lt;i&gt;pH&lt;/i&gt;&lt;span&gt;&amp;nbsp;&amp;lt; 1.5). After acid demineralization, samples of the same anthracite underwent a significant enhancement of oxidation in both acid and alkaline solutions (&lt;/span&gt;&lt;i&gt;pH&lt;/i&gt;&lt;span&gt;&amp;nbsp;= 0.4–11.5). As all the iron had been removed from the surface and the reactions were completed in a much shorter time, the oxidation mechanism must have been of a different nature than that for the untreated anthracite. A qualitative model based on the catalytic decomposition of H&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;O&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;by activated carbon sites in the coal surface is used to explain the oxidation of the demineralized anthracite.&lt;/span&gt;&lt;/p&gt;</dc:description>
