| Abstract: | In this paper, the active aluminum species leached from sludge by four chemical extraction so-lutions were studied. There are potassium chloride, ammonium acetate, hydrochloric acid and sodium hydroxide solutions. According to the different mechanisms of leaching, various chemical species of aluminum were obtained. The leaching aluminum species were determined, and the per-centage of distribution of the active aluminum species from sludge leaching was calculated. |
