Aluminium oxide is a chemical compound of aluminium and oxygen with the chemical formula Al 2 O 3. It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium(III) oxide.
Activated alumina is also widely used to remove fluoride from drinking water. In the US, there are widespread programs to fluoridate drinking water. However, in certain regions, such as the Jaipur region of India, there is enough fluoride in the water to cause fluorosis.ctivated alumina, when used as a fluoride filter, can be regenerated by a solution of lye (sodium hydroxide; NaOH), sulphuric acid (H 2 SO 4), or alum (KAl(SO 4) 2). The fluoride uptake capacity (FUC) of activated alumina can be up to 5000 mg/kg. The FUC can be determined as follows:
