Application of metal-organic frameworks in efficient mercury adsorption

The bimetallic oxide copper-manganese based metal-organic frameworks (CuMnOx/MIL-100(Fe)) were easily synthesized and used to remove elemental mercury (Hg 0 ) in flue gas.The mercury removal performance on the CuMnOx/MIL-100(Fe) was studied through a variety of characterization and analysis methods.The results suggest that the synthesized CuMnOx/MIL-100(Fe) have good crystallinity and high dispersity of constituent elements.The Hg 0 removal performance was investigated under different conditions.The increase in O2 and NO concentration can obviously promote the removal efficiency of Hg 0 .The obtained adsorption capacity is 1.128 mg/g, which is higher than the adsorption capacity of most same type adsorbents.Finally, the Hg 0 removal mechanism on the bimetallic oxide CuMnOx/MIL-100(Fe) has been proposed with various characterization analysis.The removal process of Hg 0 follows the Langmuir-Hinshelwood and Mars-Maessen mechanism.
