| Abstract: | A test was performed to revealed the transformation of Pb, Cd and other forms in pulverous coal ash by successive extraction. The result showed that the availability of Pb, Cd in the coal ash was low, while their forms were in strong bound with 48.62 mg/kg, and 0.10mg/kg for Pb and Cd, respectively. |

| Keywords: | pulverous coal ash successive extraction availability strong bound |
