Zusammenfassung: | This study proposes a method for decontamination of acid drainage water from a uranium mine, as an alternative process to lime treatment. The research embodied the recovery of uranium with an ion-exchange resin, treatment of effluent resin with lime, or with inorganic adsorbents and biosorbents. The uranium decontamination level using the resin process was 94% and allowed the recovery of this element as a commercial product. Among the inorganic adsorbents studied, phosphogypsum was effective for super(226)Ra, super(228)Ra, and super(210)Pb removal. Among the biosorbents, Sargassum sp.was superior in relation to its specific capacity to accumulate and remove super(226)Ra. |
