In the present study, the precipitation of aluminum oxide gel from sodium aluminate solution, extracted from the cans, using hydrochloric acid was studied at different pH values of 3, 7, and 12. The effect of the product calcination was also studied at different calcination temperatures. X-ray diffraction (XRD), N2 adsorption/ desorption isotherms, X-ray fluorescence (XRF) and atomic force microscopy (AFM) were used in the investigation and distinguish between the samples. The results showed that the nano crystalline gamma alumina with an average particle size of 68.56 nm, having high surface area of 311m2/g, can be obtained by a facile cost effective process.
