Introduction. In the industrial production of China, the processing of phosphate rock, volcanic eruptions, kerosene combustion and aluminum smelting will lead to flue gas emissions containing a large amount of SO 2.SO 2 is a highly irritating gas. Because SO 2 is freely soluble in water and enters the respiratory tract, it can generate …
