An analysis was performed by combining the TPD and CVAAS to identify and quantify the mercury forms in the fly ash produced from a coal-fired power plant. The TPD curve of the model sample for each mercury compound showed a unique peak temperature, and the chemical form of mercury was identified by comparing the peak temperature with that of the fly ash. A linear combination of the TPD curve of each model sample was curve-fitted to that of the fly ash. The calculated results revealed that 45% of total mercury is C-Hg in the fly ash followed by HgO, HgS, HgSO4･2HgO, HgSO4 with around 14%.
