- Abstract
The purpose of this study was to develop a resource recovery procedure for recovering nano-Al2O3from the waste aluminum electrolytic solution generated during the manufacturing of capacitors. The high concentrations aluminum contained in electrolytic solutions have a high resource potential and economic value. In this study, the co-precipitation method was used to recover the waste aluminum electrolytic solution. The results show that the purity and particle size of the recovered Al2O3were 99.943% and 0.174 μm, similar with the commercial Al2O3powder. Additionally, about 80% of the used ammonia could be recycled and reused in the reaction process. The processing technology presented in this work is thus feasible, and the application methods and economies of scale achievable with this approach are competitive and have commercial development value.
