  <dc:description>&lt;p&gt;&lt;span&gt;EXAFS spectroscopy was used to study Pb(II) and Hg(II) adsorption complexes on goethite (α-FeOOH) in the presence of Cl&lt;/span&gt;&lt;sup&gt;-&lt;/sup&gt;&lt;span&gt;. At pH 7, the dominant Pb(II) species are bonded to edges of FeO&lt;/span&gt;&lt;sub&gt;6&lt;/sub&gt;&lt;span&gt;&amp;nbsp;octahedra and are similar to complexes that occur in the absence of Cl&lt;/span&gt;&lt;sup&gt;-&lt;/sup&gt;&lt;span&gt;. At pH≤6, Pb(II)-chloro ternary complexes pedominate and are bonded to corners of FeO&lt;/span&gt;&lt;sub&gt;6&lt;/sub&gt;&lt;span&gt;&amp;nbsp;octahedra. At pH 6.5, linear Hg(OH)Cl ternary complexes predominate that are bonded to goethite through surface oxygens in a bent Hg-O-Fe geometry. In the absence of Cl&lt;/span&gt;&lt;sup&gt;-&lt;/sup&gt;&lt;span&gt;, the Hg(II) surface complexes retain this basic geometry, but an OH group replaces the chloride ion in the first coordination shell.&lt;/span&gt;&lt;/p&gt;</dc:description>
