摘　　要：介绍用无动力采样技术采集样品、离子色谱法分析SO_2污染物浓度的监测方法。国际实验室间分析结果的比对实验表明,离子色谱法具有快捷、准确及自动化程度较高等优点。该方法在城市和背景区域环境空气背景值研究,如SO_2污染物迁移规律、空气质量预测预报模型验证及远距离传输等方面具有很大的实用价值。A monitoring method of sulfur dioxide, sampled with passive sampling and determined by ion chromatography was reported. During the applycation of ion chromatography in the sample analysis, the results were compared with the active sampling technique and spectrophotometric method in the different labs. It indicated that the method was acurated, high performance and high automatization. The tecnique was the optimal choice for the research on transfer ruel of sulfur dioxide in city and background area air,verification of the prognosis of the air quality and long - range transfer.
