<p>Nitrides and fluorides in aluminum ash can easily cause environmental pollution. In order to investigate the reaction behavior of nitrogen and fluorine elements in aluminum ash, this study conducted research on the hydrolysis transformation of aluminum nitride in secondary aluminum ash in deionized water, dilute sulfuric acid solution, and sodium hydroxide solution, respectively, and analyzed the removal effect of nitrogen and fluorine elements in these three different systems. The results showed that in the sodium hydroxide system, the removal effect of nitrogen in aluminum ash was the best, with a removal rate of 94.3%. Similarly, in the sodium hydroxide system, the removal effect of fluorine in aluminum ash was the best, with a removal rate of 39.08%. By summarizing the research on the reaction behavior of nitrogen and fluorine in hazardous waste aluminum ash and discussing the experimental results, this study provides some guidance for the resource utilization of hazardous waste aluminum ash.</p> Graphical Abstract <p></p>
