Abstract
Provided are processes of removing or sequestering a basic or an acid gas from a sample by contacting the sample with a filtration media that includes a porous zirconium hydroxide impregnated with a transition metal reactant. The resulting filtration media has the ability to remove or sequester both acid and basic gases, is stable, and highly functional so as to be useful in protective equipment or other filtration systems.
