针对东北地区煤炭燃烧引起的颗粒物和SO2污染问题，采用甲醛吸收-副玫瑰苯胺分光光度法，通过对比TSP和IP样品中SO2的含量，考察时间和温湿度与SO2含量的关系。结果表明，哈尔滨市冬季大气颗粒物中SO2转化缓慢，较为稳定，但温湿度的增加有利于颗粒物中的SO2的转化，在IP和TSP中的SO2体积浓度和质量分数存在一定的差异，但总体变化趋势是一致的。大气颗粒物中S （IV）主要以SO2和HOCH2SO3H两种形式存在。

For particulate matter and sulfur dioxide (SO2) pollution caused by coal burning in Northeast, the relationship between, temperature, humidity and SO2 content with time were investigated by comparing the SO2 content of TSP and IP samples, with formaldehyde absorption - pararosaniline spectrophotometry. The results showed that in winter SO2 conversion of atmospheric particulate matter was slow in Harbin, which was more stable, but the increase of temperature and humidity was conducive to SO 2 conversion of particulate matter., There were some differences in IP and TSP that the volume concentration and mass fraction of SO 2, but the overall change trend was consistent. In atmospheric particulate matter, S(IV) mainly exists in two forms of SO2 and HOCH2SO3H.
