Description of Publication:A systematical investigation of Hg0 removal by CuS sorbent under light irradiation was conducted for the first time. The results show that light irradiation significantly inhibited the Hg0 removal efficiency of the CuS sorbent. The normalized Hg0 concentration at the reactor outlet even quickly increased from 0 to 0.45 once a lamp was turned on. Light irradiation excited a transfer of electrons on the Cu-terminated sites from inner Cu 3d orbit to outer Cu 4s orbit, and hence inhibited the formation of copper amalgam, which was supposed to be a key step in Hg0 immobilization by the CuS sorbent. Moreover, light irradiation accelerated the decomposition of copper amalgam to Hg0 which re-emitted to the gas flow.
