定电位电解法测定烟道气SO_2过程中的干扰和对策

Countermeasures against Interference in Measurement of Sulfur Dioxide in Flue Gases by Using Fixed-Potential Electrolysis Method

针对定电位电解法测定烟道气SO2过程中所存在的湿度、负压,以及NO2、CO等气体的干扰问题,依据现场监测条件,运用模拟试验方法,分析了湿度、负压和干扰气体产生干扰的原因以及对SO2测定结果的影响,探讨了消除湿度、负压和干扰气体影响的方法,并对定电位电解法测定烟道气SO2过程中存在的问题提出了具体的对策和建议。

The interference of humidity,negative pressure,and the gases,such as NO2 and CO were discussed on the measurement of sulfur dioxide in flue gases by using Fixed-Potential Electrolysis Method.Based on the in-situ monitoring,the simulation test was introduced to analyse their causes and impacts.Methods for eliminating the interference of the humidity,negative pressure and gases were discussed,the countermeasures and advice were put forward for improving the measurement of sulfur dioxide in flue gases by using...
