一氧化碳对定电位电解法测定二氧化硫的影响

Influence of Carbon Monoxide on Determination of Sulfur Dioxide by Constant Potential Electrolysis Method

采用定电位电解法测定固定污染源废气中二氧化硫,进行一氧化碳干扰实验,得出一氧化碳对定电位电解法测定二氧化硫产生正干扰,经数据分析建立数学模型,对监测数据进行人工修正,比对结果正常。

The influence of carbon monoxide on determination of sulfur dioxide in the exhaust gas of fixed source by constant potential electrolysis method was investigated.The results showed that carbon monoxide produced the positive interference on the determination of sulfur dioxide.A numerical model was established according to the rule of carbon monoxide interference.And the model was applied to monitor sulfur dioxide,the results were within the acceptance scope.
