摘要
根据目前定电位电解法出现的问题,对扩散电化学法测定固定污染源高湿度烟气中低浓度二氧化硫的能力展开研究。结果显示,扩散电化学法测定值与参比值保持较好的一致性,说明该方法不受固定污染源烟气浓度、湿度以及负压等因素的影响,对高湿烟气中低浓度二氧化硫具备较强测定能力,非常适合该状况下SO2的现场测定。但是方法也受传感器制约,适用范围受到限制。
According to the problems of the Fixed-potential electrolysis method,researching the Spread electrochemical method＇s ability that measuring the low concentration of sulfur dioxide,in the high humidity of exhaust gas from stationary source.The result show that the conclusions of the Spread electrochemical method and Reference method have better degree of consistency.It also proves that the Spread electrochemical method is not affected by the concentration,humidity and negative pressure of exhaust gas,and has more abilities to determine the low concentration of sulfur dioxide in the high humidity of exhaust gas,on the scene.This method fits to measure in this situation.But the Spread electrochemical method is limited by electrochemical sensors,so its applications is limited too.
