Effect of Temperature and Regeneration Cycles on Elemental Mercury Removal of Ag/Carbonaceous Sorbents |
| 초록 |
In this study, elemental mercury (Hg0) is a widespread concern due to its high toxic and long residence time in the environment. Ag/carbonaceous sorbents was synthesized as a high efficient and recyclable sorbent for Hg0 removal. Ag particles were doped on the surface of carbonaceous sorbents by a facile in situ chemical synthesis method. XRD and TEM results showed that Ag nanoparticles successfully grew on the surface of carbonaceous sorbents. The performance of Ag/carbonaceous sorbents was tested under a fix-bed reactor and the results showed that it could completely capture Hg0. The Hg0 removal efficiency decreased from 94% to 60% when the temperature increased from 25 to 100oC, respectively. The adsorption capacity of Hg0 had no degradation after six cycles. The high Hg0 capacity and recyclability make the Ag/carbonaceous sorbents a candidate for the removal at ambient temperature. |
