环境空气中二氧化硫样品保存条件的探讨

Discussion on the Storage Conditions of Sulfur Dioxide Samples in Ambient Air

二氧化硫是环境空气质量监测的重要指标之一,采集后样品的稳定性对数据的准确性至关重要。本文通过对保存温度、保存时间、保存方式三个因素进行比对实验,探讨二氧化硫样品的保存条件。实验结果表明,二氧化硫样品采集后,避光与冷藏是最佳的保存途径。

Sulfur dioxide is one of the important indicators of environmental air quality monitoring,and the stability of samples after collection is critical to the accuracy of data.In this paper,the storage conditions of sulfur dioxide samples are discussed by comparing the storage temperature,storage time and storage method.The experimental results show that the best way to store sulfur dioxide samples is to avoid light and refrigerate them.
