摘　　要：探讨了家用除湿机作为空气水溶性物质采集器的可行性。通过离子色谱仪对冷凝水离子成分的分析,并与空气总悬浮微粒(TSP)可溶性化学成分的对比,发现水汽中大部分阴阳离子的含量只比TSP低1个数量级。但TSP中一般检测不出亚硝酸根,而在水汽中则可检测出亚硝酸根离子,且水汽中亚硝酸根离子的浓度与取样位置的大气环境质量有关。A new taking sample method by home dehumidizer has been developed, and validated the feasibility of the method as a sampler of atmospheric soluble substance. In order to explore the relationship between condensate water and atmospheric air quality, two observations have been carried out in this research: which comprise the contrast between chemical components of condensate water and soluble chemical components of total suspended particle (TSP). The concentration of NO^-_2 was found in condensate water, it has relationship with atmospheric air quality.
