An enhanced MoS2/C10TAB/H2O system was built and investigated for Hg0 removal based on strengthening the Hg0 gas-liquid mass transfer. The results showed that adding 7mg/L C10TAB can improve the Hg0 removal efficiency from 76.5 to 88.7% as decrease of the solution surface tension. Keeping 2000rpm of stirring rate accelerated the renewal rate of gas-liquid interface, thereby enhancing Hg0 removal. SO2 slightly promoted the Hg0 removal efficiency to 91% because of the absorption of SO2 causing a decrease in the solution pH from 6.9 to 4.3. NO participated in Hg0 removal reactions but not removed in this system which visibly enhanced the Hg0 removal efficiency to 94%. The Hg mass transfer kinetics were analyzed to determine how C10TAB promoted Hg0 removal. The Hg-TPD, Hg fate, and species results revealed that Hg0 was first oxidized to Hg2+, then bonded with S to generate HgS and enrich on the MoS2. Therefore, improving the Hg0 gas-liquid mass transfer can enhance Hg0 removal in MoS2/H2O system, which can provide reference for purification of other insoluble pollutants in absorption system.
