采用玻璃纤维滤筒采集电镀废气中的硫酸雾，采样后用离子色谱法进行了测定。实践表明：当采样体积为400L时，硫酸雾的检出限为o．08mg／m2，实际水样的加标回收率为95．3％～104％。方法操作简便快速、准确、灵敏度高，完全满足环境监测对电镀废气中硫酸雾的测定。%This article uses Ion Chromatography method to determine sulfuric acid mist in waste gas of plating surface finishing industry. When the sampling volume is 400L, the detection limit of sulfuric acid mist is 0.08 mg/m3,and the recovery rate is 95.3%-104%. The method is proved to be simple,fast,accurate and sensitive. And it could meet the actual demands in the environmental analysis of sulfuric acid mist in waste gas of plating & surface finishing industry.
