Abstract:
Techniques for reduction of copper from aqueous streams using an iron promoted activated alumina are disclosed. An adsorbent media composition that reduces copper levels in an aqueous feed stream includes an iron containing activated alumina. A process for reducing copper levels in an aqueous fluid using an iron promoted activated alumina sorption media includes contacting the aqueous fluid containing a copper contaminant with the iron promoted activated alumina to achieve reductions in copper from the aqueous fluid.
