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

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 Fixed-Potential Electrolysis Method.
