Micrometric-sized Boehmite obtained from urban waste
Abstract
In this work, the production of aluminum hydroxide by leaching aluminum scrap in an alkaline NaOH solution was investigated. Two precipitations were carried out at different pH values. In the first precipitation, the impurities of the aluminum scrap were separated; in the second precipitation, micron-sized aluminum hydroxide particles were obtained. Chemical equilibrium diagrams were shown to be useful in explaining the formation of different chemical species during aluminum scrap treatment, including solid, ionic, and aqueous chemical species. The solid chemical species, mostly impurities, were separated by filtration, while the ionic and aqueous ones were used to produce an aluminum hydroxide solution. Micron-sized aluminum hydroxide particles were obtained by neutralizing the solution, followed by separation and drying. The specific surface of the powders was 69.83 m2/g, results consistent with the results of the crystallographic analysis. These results suggest that this process could be an efficient way to produce micron-sized aluminum hydroxide particles from urban waste.
