| 摘 要： | 对过渡金属离离子催化氧化脱除烟气中ＳＯ２进行了研究。实验发现Ｍｎ（ＩＩ）对ＳＯ２的氧化有很强的催化作用，而且在吸收液中有Ｆｅ（Ⅲ）参加时有明显协同催化作用。Ｆｅ（Ⅲ）能将Ｍｎ（ＩＩ）氧化成为Ｍｎ（Ⅲ），从而将ＳＯ_３~（２－）加速氧化成为ＳＯ_３~－，以引发催化周期。通过实验得出当吸收液中Ｍｎ２＋离子浓度为０．０１ｍｏｌ／Ｌ，Ｆｅ２＋离子浓度为５×１０~（－３）ｍｏｌ／Ｌ时，脱硫效率可达到９９％。

| Abstract: | Removal of SO2 from flue gas based on catalyzed oxidation with transitional mental ion is investigated. Results indicate that Mn2+ plays a significant catalytic role, but remarkable synergistic effect actually occurs in the presence of Fe2+. It is suggested that Mn (II) can be oxidized to Mn (III) by Fe (III), which accelerates the oxidization processes of SO_3~(2-) to SO_3~- radicals and initiates the catalytic cycle. With concentrations of Mn (II) of 0.01 molesL-1 and Fe (II) of5?*10-3mo1esL-1, desulfurized efficiency of 99% was obtained. |
