Study of the adsorption mechanism on the surface of a ceramic nanomaterial for gaseous Hg(II) removal.

Stable Hg(II)-containing flue gas has been successfully simulated by the plasma oxidation of Hg(0), and an effective solution for Hg(0) mercury fumes was obtained by combining the plasma with a ceramic nanomaterial. Characterization tests showed that the ceramic nanomaterial was mainly composed of silicon dioxide (SiO) with other minor constituents, including potassium mica (KAlSiO), iron magnesium silicate (FeMgSiO) and dolomite (CaMg(CO)). The nanomaterial had many tube bank structures inside with diameters of approximately 8-10 nm.
