A highly porous material produced from dehydroxylated aluminium hydroxide. Is used as a desiccant and as a filtering medium.

A form of aluminium oxide that readily absorbs moisture and is commonly used as a drying agent. For example, wet instrument air may be passed through a bed of activated alumina pellets, where the alumina removes the moisture from the air.

See Technology

A charged form of aluminum, used with a synthetic, porous media in an ion exchange adsorption process to remove charged contaminants.

Activated alumina is a filter media made by treating aluminum ore so that it becomes porous and highly adsorptive. Activated alumina will remove a variety of contaminants, including excessive fluoride, arsenic, and selenium.

Activated Alumina is a form of aluminum oxide used as a desiccant (dryer) for gases. It is also used as a carrier for potassium pernanganate when the latter is used as a chemisorber.

Chemical used as a drier or desiccant.

Chemical which is a form of aluminum oxide. It is used as a drier or desiccant.
