摘要
The absorption behavior of Hg-0 was studied experimentally by using sodium chlorite (NaClO2) as the absorbent in a bubble reactor. Primary influencing factors on the removal of Hg-0 such as NaClO2 solution concentration, solution hydrogenion concentration (pH), reaction temperature, the concentration of Hg-0, and other components in the flue gas, such as O-2, SO2, and NO, were investigated. Approximately 65% removal of elemental mercury can be achieved under optimal experimental conditions. The removal mechanism of Hg-0 was proposed by analyzing Hg2+ concentration in the spent absorption solution and comparing the electrode potentials between NaClO2 species and Hg2+/Hg-0.
