  <dc:description>The method is an adaptation of a procedure described by Betz and Noll&lt;sup&gt;1&lt;/sup&gt; in 1950. Calcium and magnesium are determined by visual titration using Versene (disodium ethylenediamine tetraacetate) with Murexide (ammonium purpurate) as the indicator for calcium and Eriochrome Black T as the indicator for magnesium.</dc:description>
