摘要
建立了以玻璃纤维膜-KB120气溶胶采样器采集大气中甲磺酸的采样方法;以0.1mmol·l^(-1)H_3BO_3/0.1mmol·l^(-1)Na_2B_4O_7为淋洗液的甲磺酸离子色谱分析方法.分析方法的精密度和准确度分别为5%和4%.并实测了青岛冬季大气气溶胶中MSA,SO_4^(2-)和NO_3^-的平均浓度分别为0.10μg·m^(-3),30.40μg·m^(_3)和17.98μg·m^(-3).
The ambient methanesulfonic acid (MSA)sampling method is established using glass filter and KB-120 aerosol collector; as well as the analysis of MSA using ion chromatography (0. 1mmol·l-1 H3BO3/0.1mmol·l-1 Na2B4O7 as the eluent). The precision and accuracy of MSA determination method are 5% and 4% . Winter ambient aerosol in Qingdao near shore was measured, the average concentrations for MSA, SO2-4 and NO-3 are 0.10μm·m-3, 30.40μm·m-3 and 17.98μg·m-3, respectively.
