What is Activated Alumina?

Activated alumina is a highly porous material made of aluminum oxide. This material is manufactured through the dihydroxylation of aluminum hydroxide. The surface area of this material is very high, about 200 square meters per gram. Activated alumina is important as a desiccant that can keep substances dry by absorbing water from surrounding air. Moreover, this material can be used as a filter of fluoride, arsenic and selenium in drinking water.

Activated alumina has a large surface-area-to-weight ratio. This is because this material has many “tunnel-like” pores.
