| 摘 要： | 讨论酸性条件下Ｆｅ＾３＋液相氧化ＳＯ２的几何可能反应机理，设计了不同的缓冲和非缓冲Ｆｅ＾３＋溶液脱硫试验。通过对不同反应体系ＳＯ２吸收特性的测量，得出了反应符合半导体或过渡态金属的催化机理，液相氧化反应的速率受Ｆｅ＾３＋的老化进程所控制，从而为低浓度Ｆｅ＾３＋溶液烟气脱硫和解释雾水酸化现象提供了理论基础。

| Abstract: | The experiment was designed for Fe 3+ aqueous oxidation SO 2 in buffered or nonbuffered acid solution and given the discussion on the several possible mechanisms of this reaction.With the measurement of the SO 2 absorption in the different reaction systems designed,the reaction was identified as the semi conductor or transient metal mechanism,and the kinetic rate was controlled by the progress of Fe 3+ aging.Such result provided the theoretical basis for the use of dilute Fe 3+ solution in the flue gas desulfurization and the explanation of fog water acidification. |
