The paper reported novel synthesis of alumina AlxOy Sub-Microstructure Particles Using In-House Methods. The structure was synthesized from aluminium oxide by in-house prepared method. The synthesis was performed using caustic soda (NaOH) assisted, pure aluminium was dissolved in pre-prepared solution of DI, H2O4, NaOH. AlxOy was prepared in crucible via 5 different pH solutions of DI, H2O4, NaOH. The pure aluminium powder was prepared from 2 NaAl(OH)4. The process passed through three reactions; Oxidation Al(OH)y, evaporation AlxOy, and dissolution 2NaAl(OH)z: Uniformly distributed activated was synthesis with the average diameter of the alumina AlxOy sub-microstructures between 10.34 to 40.2μm were realised. The prepared, activated alumina was tested against three columns of 1,260 cm3, 675 cm3 and 525 cm3 with 27 samples of different content of activated. It was found, all the three columns show to total reduction of the lead from the water with increase content of activated alumina.
