摘要
通过对两种不同方法测定废气中的二氧化硫的比较,研究发现一氧化碳气体导致定电位电解法测定二氧化硫浓度偏高,对非分散红外吸收法测定影响不大。研究结果表明:对于电化学法测定二氧化硫,废气中一氧化碳浓度越高对二氧化硫浓度的测定结果偏差越显著;当一氧化碳浓度一定时,二氧化硫浓度越低,受影响越大。
The study has compared the two sulfur dioxide concentrations obtained from the sulfur dioxide measurement by using the two different methods： the constant potential electrolysis and the non-dispersive infrared absorption method, and has found that the carbon monoxide gas causes the sulfur dioxide concentration measured by using the con- stant potential electrolysis to rise, but it has little effects on the non-dispersive infrared absorption method. The results have shown that when the constant potential electrolysis is used to measure the sulfur dioxide concentration, the higher the concentration of the carbon monoxide in the waste gas is, the more significant the deviation in the sulfur dioxide measurement is; meanwhile, when the carbon monoxide concentration is at a given level, the lower the sulfur dioxide concentration is, the more greatly the sulfur dioxide concentration is affected.
