利用离子色谱法（IC）对莆田市的PM2.5中的水溶性阴离子（F-、Cl-、No3-、So42-）进行了分析测定,并对相关的条件进行探讨.通过对采样滤膜的比较,发现用过氯乙烯滤膜优于超细玻璃纤维滤膜；通过对提取方法的比较,发现用超声波提取效果优于加热搅拌提取和静置提取；通过提取效率的实验,发现用超声波提取两次试液就已经提取完全.同时实验表明,莆田PM2.5浓度已经轻微超标,且其中的水溶性阴离子主要为No3-、So42-,No3-主要来源为汽车尾气排放,So42-则是由于煤的燃烧.

The water solubleanions(F-,Cl-,No3-,So42-)in PM2.5in Putianwere measured and analyzedusingion chromatography(IC),and relevant factors were discussed.By comparison ofsampling filtermembranes, it was foundthat perchloroethylenefiltermembrane is better than the ultra-fine glassfiber filtermembrane;by comparison of theextraction methods,it was found thatthe effect in ultrasonic extractionmethod is better than that ofheatingand stirring extractionmethod andstaticextraction method;by theexperimentof extraction efficiency,it was found thatthe desired solutionis fully extractedin two extractions withthe ultrasonic extraction method.It was also indicated in the experiments thatthe PM2.5 concentration in Putianexceeded the standardslightly,in which thewater solubleanions were mainlyNo3-and So42-: the No3-mainly came from vehicle emissionswhile the So42-came from the combustion of coal.
