Abstract：Chemical speciation of seven heavy metals of flyashes in incinerator was quantitatively tested using ICP-AES. Results showed that ICP-AES procedure could carry out quick, exact and high precision experiments. RSD ratio for most detected metals was lower than 3% while few metals present a comparatively high RSD when whose content was near the detection limits. The recovery ratio was 85.7%-100.63% flyashes were found to have high content of Zn, Pb. Cd, Cu, Mn, Pb and Zn existed mostly as carbonates and were leachable, while Cr and Ni were combined to metal oxides substrates and present immobilization characteristics.
