摘要
用Filter badge SO2捕集空气中SO2。用双氧水将捕集到的SO2氧化成SO42-,再用离子色谱法测定SO42-的浓度,按公式f SO2=2082×103×(T/τ)X计算,即可得到捕集时间内的平均SO2浓度f SO2(ppb)。
Trapping the Sulfur Dioxide in the Atmosphere by Filter badge SO2, The Sulfur Dioxide is oxidized forming Sulfate Radical with the Hydrogen Peroxide Solution. Then Determination of sulfate concentration. According below formula to calculate：f SO2 = 2082 ×10^3 × （ T/τ ） X, Can obtained with the average concentration of the Sulfur Dioxide in the trapping time.
