A novel pre-oxidation method for elemental mercury removal utilizing a complex vaporized absorbent

Simultaneous removal of SO 2 , NO and Hg 0 through an integrative process utilizing a cost-effective complex oxidant

“…122) (ECOM-J2KN, RBR Company, Germany). The experimental procedure was specifically described in our previous work [14]. The removal efficiencies were calculated according to the concentrations of Hg 0 , SO 2 and NO before and after reaction (Eq.…”

Integrative process of preoxidation and absorption for simultaneous removal of SO2, NO and Hg0

“…8 (C), when the NO concentration is within 250 mg/m 3 , the Hg 0 removal efficiency decreases by 3%, as the NO concentration further increases from 250 to 1000 mg/m 3 , an unconspicuous decrease of Hg 0 removal was observed. The initial decrease of Hg 0 removal was mainly due to the competitive reactions of NO and Hg 0 for the limited oxidants [12,13,40]. The reasons for the unconspicuous decrease of Hg 0 removal were as followed: on the one hand, an increase of NO concentration would result in more NO oxidation, which was unfavorable for Hg 0 oxidation; however, on the other hand, NO 2 and NO 3 À formed from NO oxidation would adversely promote Hg 0 oxidation (Eq.…”

“…Tan Zengqiang et al [41] were attempted to modify the bamboo charcoal for Hg 0 removal, and found that HNO 3 had a satisfactory performance on Hg 0 oxidation. In addition to these references, in our previous work [40], we investigated the roles of NO 2 and the derivant in Hg 0 removal through a transient response experiment, and finally determined the promotional effects of N-containing species on Hg 0 oxidation.

Synthesis of Ag‐modified TiO2 nanotube and its application in photocatalytic degradation of dyes and elemental mercury

“…Finally, due to the affinity among HgO and Hg 0 , entered fresh Hg 0 would be adsorbed onto HgO of TNT surface. However, Cl − on the surface of TNT also can react with OH• and h + to generate •ClOH ‐ and Cl 2 , and then oxidation of Hg 0 . Moreover, Cl 0 atoms that oxidize Hg 0 to Hg 2+ can be created because of h + and Cl − combination on the surface of AgCl .…”
