Removal of Hg[sup]0 in wet FGD by catalytic oxidation with air - A contribution to the development of a process chemical model

The highlights of the paper are: - Modification of FGD chemistry prevents reduction of Hg(II) and enables oxidation of Hg(0) thus retaining mercury in solution. - Mercury in FGD can be oxidized by catalytic reactions with transition elements. - Presence of ligands can stabilize oxidized mercury in FGD system. - Chemical model developed can be used for the predictions of reactions

Development of the method for temperature fractionation of mercury in solid samples

The method for temperature fractionation was checked and validated. A number of parameters can influence the T at which Hg compounds decompose, among those the solid substract plays the major role. Critical assessment of the currently existing methods are discussed. We also concluded that method based on AAS detection are limited due to poor understanding of Hg breakdown processes at elevated temperatures.

Stability of mercury compounds at high temperatures

Pure Hg compounds were investigated at higher T. We discovered that the purity of Hg compounds is an issue, especially when such compounds are to be used for calibration purposes, particularly the Hg chloride seem to be very sensitive at normal atmospheric conditions.
