Abstract
Preparing a porous hybrid media includes contacting porous media (e.g., strong base ion-exchange media) with an aqueous solution including aluminum ions to yield a aluminum-ion-containing porous media, contacting the aluminum-ion containing porous media with a reducing agent to impregnate elemental aluminum in the porous media, and oxidizing the elemental aluminum to yield a porous hybrid media including aluminum hydr(oxide) impregnated in the porous media. In some cases, a pH of an aqueous mixture including the aluminum-ion-containing porous media may be adjusted to form a floc including aluminum hydroxide, and the aluminum hydroxide-containing porous media may be contacted with a reducing agent to yield a porous hybrid media including aluminum hydr(oxide) impregnated in the porous media. The porous hybrid media may advantageously be prepared at low temperature (e.g., room temperature).
