| 中文摘要 |
| 讨论酸性条件下Fe3+液相氧化SO2的几种可能反应机理,设计了不同的缓冲和非缓冲Fe3+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Fe3+的老化进程所控制,从而为低浓度Fe3+溶液烟气脱硫和解释雾水酸化现象提供了理论基础。 |
| 英文摘要 |
| The experiment was designed for Fe3+ aqueous oxidation SO2 in buffered or nonbuffered acid solution and given the discussion on the several possible mechanisms of this reaction.With the measurement of the SO2 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 Fe3+ aging.Such result provided the theoretical basis for the use of dilute Fe3+ solution in the flue gas desulfurization and the explanation of fog water acidification. |
