摘　　要：测定环境空气中二氧化硫最常用的方法是甲醛吸收-副玫瑰苯胺分光光度法。在采用甲醛法测定环境空气中二氧化硫的实验中,玻璃器皿的洁净度、试剂的有效性、反应条件等均会对实验结果产生影响。针对以上因素,对实验过程中应注意的问题进行了归纳总结,以提高测定结果的准确性。The most common pararosaniline spectrophotometry method of determination of sulfur dioxide in the air was formaldehyde absorption - The formaldehyde method was used to determine sulfur dioxide in ambient air experiments, glassware cleanliness, effectiveness reagents, and reaction conditions, etc., which would influence the results of the experiment. For the above factors, the issue should be taken during the experiment were summarized in order to improve the accuracy of measurement results.
