Mercury forms in fly ash and desulfurization gypsum produced from the coal-fired power plant were analyzed. A combination of temperature programmed desorption (TPD) and cold vapor atomic absorption spectrometry (CVAAS) was applied and the optimum operating condition was determined to clarify the forms of mercury. TPD curves of mercury obtained for the ash and gypsum were analyzed qualitatively and quantitatively with comparing to the peak temperature and linear combination of TPD curves of model mercury compounds. The results indicated that mercury in the desulfurization gypsum was mainly composed of HgCl2 and the adsorbed one by unburned carbon.
