Activated alumina spheres are porous and highly dispersed solid materials with a large specific surface area and adsorption capacity on the microporous surface. It is insoluble in water and organic solvents, but soluble in strong acids and bases, odorless, tasteless, and non-toxic. Activated alumina is divided into six types according to its different uses: adsorbent, defluoriner, hydrogen peroxide specific, dechlorination agent, catalyst carrier, and air separation specific adsorbent.
