摘要
The bimetallic iron–copper based metal–organic frameworks (FeCu-MOFs) with rich chlorine were synthesized and used to remove gaseous elemental mercury (Hg0). The mercury removal performance on the bimetallic porous material was studied based on a variety of characterization and analysis methods. The results suggest that the synthesized FeCu-MOFs have good crystallinity and high element dispersity. The bimetallic MOFs materials have a high Hg0 removal efficiency (higher than 90% in various conditions). O2, HCl, and NO in the flue gas can improve Hg0 removal efficiency. Moreover, FeCu-MOFs materials have good abilities to resist water vapor and SO2 poisoning. According to the adsorption kinetics analysis, the mercury equilibrium adsorption capacity of FeCu-MOFs is 12.27 mg/g. Finally, the Hg0 removal mechanism on the bimetallic FeCu-MOFs has been proposed. The whole mercury removal process conforms to the Langmuir–Hinshelwood mechanism.
