| 摘 要： | 由于SO2和NO2都是具有氧化还原能力的气体,通过热力学计算得出SO2和NO2有相互作用的可能,通过实际测量已知浓度的SO2和NO2混合气体,结果表明SO2和NO2在气相中较短时间内发生氧化还原反应可忽略不计,在湿法同时脱硫脱硝工艺中它们之间的一系列反应是在液相中进行的。可以用碘量法和盐酸萘乙二胺分光光度法分别测量混合烟气中的SO2和NO2。实验结论将为湿法同时脱硫脱硝工艺提供一定的理论基础。

| Abstract: | Added by experiments and thermodynamics calculation, it is found that there exists the possibility of interaction between SO2 and NO2; oxidation/reduction reaction between SO2 and NO2 can be neglected in a short time; and in the process of wet simultaneous desulfurization-denitrification, a series of reaction between SO2 and NO2 take place in aqueous phase. |
