  <dc:description>&lt;p&gt;&lt;span&gt;A phosphate glass has been found to have a significant electrode specificity toward alkaline-earth ions. The order of selectivity is 2H&lt;/span&gt;&lt;sup&gt;+&lt;/sup&gt;&lt;span&gt;&amp;nbsp;&amp;gt; Ba&lt;/span&gt;&lt;sup&gt;++&lt;/sup&gt;&lt;span&gt;&amp;nbsp;&amp;gt; Sr&lt;/span&gt;&lt;sup&gt;++&lt;/sup&gt;&lt;span&gt;&amp;nbsp;&amp;gt; Ca&lt;/span&gt;&lt;sup&gt;++&lt;/sup&gt;&lt;span&gt;&amp;nbsp;&amp;gt; 2K&lt;/span&gt;&lt;sup&gt;+&lt;/sup&gt;&lt;span&gt;&amp;nbsp;&amp;gt; 2Na&lt;/span&gt;&lt;sup&gt;+&lt;/sup&gt;&lt;span&gt;&amp;nbsp;&amp;gt; Mg&lt;/span&gt;&lt;sup&gt;++&lt;/sup&gt;&lt;span&gt;. Exchange properties are discussed in relation to possible structure. Its use to determine activity of Ca&lt;/span&gt;&lt;sup&gt;++&lt;/sup&gt;&lt;span&gt;&amp;nbsp;in natural systems containing Mg&lt;/span&gt;&lt;sup&gt;++&lt;/sup&gt;&lt;span&gt;&amp;nbsp;is suggested.&lt;/span&gt;&lt;/p&gt;</dc:description>
