摘　　要：Mercury(Hg)pollution has been a global concern in recent decades,posing a significant threat to entire ecosystems and human health due to its cumulative toxicity,persistence,and transport in the atmosphere.The intense interaction between mercury and selenium has opened up a new field for studying mercury removal from industrial flue gas pollutants.Besides the advantages of good Hg^(0) capture performance and lowsecondary pollution of the mineral selenium compounds,the most noteworthy is the relatively low regeneration temperature,allowing adsorbent regeneration with low energy consumption,thus reducing the utilization cost and enabling recovery of mercury resources.This paper reviews the recent progress of mineral selenium compounds in flue gas mercury removal,introduces in detail the different types ofmineral selenium compounds studied in the field ofmercury removal,reviews the adsorption performance of various mineral selenium compounds adsorbents on mercury and the influence of flue gas components,such as reaction temperature,air velocity,and other factors,and summarizes the adsorption mechanism of different fugitive forms of selenium species.Based on the current research progress,future studies should focus on the economic performance and the performance of different carriers and sizes of adsorbents for the removal of Hg^(0) and the correlation between the gas-particle flow characteristics and gas phase mass transfer with the performance of Hg^(0) removal in practical industrial applications.In addition,it remains a challenge to distinguish the oxidation and adsorption of Hg^(0) quantitatively.
