Abstract
Activated Alumina (AA) prepared from Alum Sludge (AS) and used in removal of fluoride from
aqueous solutions. The capacity of AA in the adsorption of fluoride from water was found to
be 17.75 mg/g. The maximum efficiency of fluoride adsorption was 96% at optimum condition
(C ¼ 5 mg/L, pH ¼ 7, t ¼ 20 min and adsorbent dosage ¼ 5 g/L). Based on the results, it can be
concluded that conversion of AS to AA can be a method to recycling of AS. Also AA can be used for
adsorption of fluoride from aqueous solutions. So AS as a harmful substance to the environment
turns into AA as a usable material in water treatment
