| Abstract: | In this paper, the active aluminum species leached from red kaoline, a kind of Chinese traditional medicine, by four chemical extraction solutions were studied. Potassium chloride, ammonium acetate, hydrochloric acid, and sodium hydroxide solutions were used for extraction. According to different mechanisms of leaching, various chemical species of aluminum were obtained. The leaching aluminum species were determined, and the percentage distribution of active aluminum species from the Chinese traditional medicine was calculated. |
