摘要
目的:通过离子色谱法对废气中二氧化硫进行检测分析。方法:先进行当前废气中二氧化硫实时浓度值的计算,结合离子色谱法设置色谱柱及对应的检测参数,以此为基础,调整检测装置,设置间隔,通过对二氧化硫峰高波动比以及摩尔质量,测定出二氧化硫变异相关系数,进而最终得出相对检测偏差。结果:针对5个区域对应的5个废气检测反应管的验证,二氧化硫相对检测偏差分别是0.16、0.18、0.21、0.28、0.37。结论:二氧化硫相对检测偏差的高低与浓度及变动的幅度存在正向的关系,二氧化硫实时浓度值以及峰高波动比提升,检测偏差增加;二氧化硫实时浓度值以及峰高波动比降低,检测偏差减小。
Objective:To detect and analyze sulfur dioxide in exhaust gas by ion chromatography.Method:First,calculate the real-time concentration value of sulfur dioxide in the current exhaust gas,and set the chromatographic column and corresponding detection parameters using ion chromatography.Based on this,adjust the detection device and set intervals.By measuring the fluctuation ratio of sulfur dioxide peak height and molar mass,determine the correlation coefficient of sulfur dioxide variation,and finally obtain the relative detection deviation.Result:For the validation of 5 exhaust gas detection reaction tubes corresponding to 5 regions,the relative detection deviations of sulfur dioxide were 0.16,0.18,0.21,0.28,and 0.37,respectively.Conclusion:There is a positive relationship between the relative detection deviation of sulfur dioxide and the concentration and amplitude of changes.The real-time concentration value and peak height fluctuation ratio of sulfur dioxide increase,and the detection deviation increases.The real-time concentration value and peak height fluctuation ratio of sulfur dioxide decrease,and the detection deviation decreases.
