摘要
为探索空气冷凝水与大气环境质量之间的关系 ,通过离子色谱仪等对冷凝水与降雨中化学成份的分析 ,并考察降雨前后空气冷凝水中可溶性化学成份的对比 ,发现空气冷凝水与降雨的化学成份显著相关 ,且冷凝水中大部分阴阳离子的含量比雨水低 1个数量级 ,降雨过程中的水汽冷凝水化学成份与降雨前相比有些成份下降 ,而有些则增加。
Ion chromatography was used to analyze air condensate and chemical component of rainfall, for purpose of exploring relationship between condensate water and air quality. Through comparison of air soluble substance in air condensate before and after rainfall, air condensate was found to be obviously related with chemical component of rainfall, and most of cation and anion concentration in aqueous vapour was just about 10% of rainfall. Some chemical components in air condensate were decreased while some increased after rainfall.
