Abstract: Adsorbents for removing H2S, other odor-causing compounds, and other acid gases from gas streams, as well as methods for manufacturing and using adsorbents, are provided. Adsorbents comprise a porous media in which at least one metal oxide is primarily distributed on or over the surface of the pores of the media. In an example, the porous media is activated carbon and the metal oxide is magnesium oxide. The adsorbents of the present invention are particularly useful for removing odor caused by hydrogen sulfide and organic sulfinur compounds that are common at municipal waste treatment plants, paper mills and industrial plants.

Abstract: Adsorbents and methods for removing cations of heavy metals from a medium are provided. The adsorbents comprise a porous media in which at least one oxygen-containing compound of iron, copper, aluminum, zirconium, titanium and combinations thereof is incorporated. The oxygen-containing compound may be incorporated into the porous media by impregnation or dispersion of a suitable precursor of such a compound. The precursor may be further treated to yield the oxygen-containing compound. Such adsorbents are particularly useful for removing lead and/or other metal cations from the environment and may be used in treating drinking water sources.
