| 摘 要： | 针对钢铁企业烧结工段烟气的特点,对可能影响碘量法、定电位电解法SO_2监测结果的因素进行分析,并提出相应的对策。研究表明:定电位电解法受CO干扰较大,根据数学模型修正后,可进行SO_2浓度的快速估算;碘量法受吸收液温度、分析时间等因素影响较大,需要现场监测人员和分析人员严格控制采样和分析条件。

| Abstract: | According to the characteristics of the flue gas from sintering process of iron and steel enterprises, the influence factors on monitoring results of SO2 by iodometric method and fixed-potential electrolysis method were analyzed, and the corresponding counter-measures were put forward. The results showed that the fixed-potential electrolysis method are apt to be interfered by CO, but if cor-rected according to the mathematical model, the method can be used for rapid estimation. While the iodometric method is greatly in-fluenced by analysis time and the temperature of absorption liquid, so stringent sampling and analysis conditions should be con-trolled. |
