Resumo: | The coprecipitation of Cd, Co and Eu from seawater onto ferric hydroxide was studied, using the radioactive tracers &lt;sup&gt;109&lt;/sup&gt;Cd, &lt;sup&gt;60&lt;/sup&gt;Co and &lt;sup&gt;152-154&lt;/sup&gt;Eu, as a function of the pH, the concentration of the collector iron, the concentration of the metal spike and the aging of the internally formed precipitate. For preconcentration purpose, a pH 9 and a 35 ppm iron concentration appeared to be suitable. At pH 8, the natural pH of seawater, the distribution coefficients for Cd, Co and Eu are 10&lt;sup&gt;4.5&lt;/sup&gt;, 10&lt;sup&gt;5&lt;/sup&gt; and 10&lt;sup&gt;7&lt;/sup&gt;, respectively.
