烟气氯化氢分析中的干扰因素及消除

Disturbance to the hydrogen chloride analysis in flue gas and its elimination

在火电厂烟气成分分析中 ,采用硝酸银容量法测定烟气氯化氢时发现主要干扰成分是二氧化硫 ;

According to the analysis experience on the flue gas composition,using silver nitrate solution titration to analyze the hydrogen chloride in the flue gas indicated that the main disturbance factor is sulphur dioxide.It was also found that the sulphur cyanic acid spectrophotometric method is not applicable to the hydrogen chloride analysis in the flue gas in coal fired power plant.
