Mercury form analysis was carried out by using temperature programed desorption and cold vapor atomic absorption spectrometry. Model samples of mercury-adsorbed carbon were prepared using activated carbon and unburned carbon separated from coal fly ash. The mercury of adsorbed by unburned carbon (UC-Hg) and activated carbon (AC-Hg) showed different desorption temperature. The TPD curves of UC-Hg and AC-Hg were changed with concentration of mercury in the liquid during adsorption. Considering both forms of UC-Hg and AC-Hg, the quantitative analysis of various mercury forms in desulfurization gypsum can be achieved.
