Filter badge SO_2捕集-离子色谱法测定空气中二氧化硫

摘要

用Filter badge SO_2 捕集空气中SO_2.用双氧水将捕集到的SO2氧化成SO42-,再用离子色谱法测定SO_4~(2-)的浓度,按公式f SO_2=2082×10~3×(Τ/τ)X计算,即可得到捕集时间内的平均SO_2浓度f SO_2 (ppb).%Trapping the Sulfur Dioxide in the Atmosphere by Filter badge SO_2 ,The Sulfur Dioxide is oxidized forming Sulfate Radical with the Hydrogen Peroxide Solution. Then Determination of sulfate concentration. According below formula to calculate: f SO_2 = 2082×10~3×(Τ/τ)X,Can obtained with the average concentration of the Sulfur Dioxide in the trapping time.
