Steel slag has the structural characteristics of loose and porous，and rich in alkaline oxides such as CaO and MgO，so it is highly alkaline in the solution and has strong acid neutralization ability，which can effectively remove sulfur dioxide from flue gas and realize effective desulfurization.At present，steel slag-based desulfurization absorption materials are mainly used in wet desulfurization processes.The basic mechanism is the mass transfer between the gas phase and the liquid phase，which contains three steps：1）SO2 enters the liquid phase from the gas phase；2）the alkaline substance is dissolved out of steel slag，and 3）chemical reaction occurs between SO2 and alkaline substances in the liquid phase.However，the overall desulfurization efficiency is mainly affected by the first two steps.The main factors include inlet SO2 mass concentration，liquid-gas ratio，slurry pH，reaction temperature，steel slag particle size and so on.However，at present，the research on the influence mechanism of other components in steel slag except CaO and MgO on the desulfurization effect is not enough.Therefore，it is necessary to actively explore the synergistic mechanism of different chemical components in steel slag in the desulfurization absorption process，consolidate the theoretical basis of steel slag for flue gas desulfurization and then realize the industrial application of steel slag desulfurization.
