Nano sized alumina was synthesized by chemical route using Al(NO3)3, and triethanol amine. The synthesized alumina was characterized by XRD and SEM and EDX analyses. XRD study shown that the average crystallite size was calculated to be 10 nm, while from SEM the grain size was found to 0.37 µm.  Defuoridation experiments were carried out taking different concentration of fluorides 3 mg/l, 5 mg/l, 10 mg/l and 20 mg/l using different adsorbent dose i.e. nano alumina. When the initial concentration of fluoride increases the percentage of the fluoride removal also increases with small adsorbent dose.
