Abstract
The boehmite precursors with high surface area have been obtained using aluminum isopropoxide (AIP) and deionized water as starting materials and have been transformed into α-alumina after annealing at 1200oC for 2 hrs. Aluminum isopropoxide was purified with hydrolysis reaction with isopropyl alcohol for 1 hr by stirring at 120 rpm at 80oC. A highly selective and very sensitive spectrophotometric method was used to determine the trace amounts of each element in the synthesized alumina samples.

Keywords: Alumina, Aluminum isopropoxide, Boehmite precursor, Sol-gel method, Interfering effect.
