甲醛缓冲溶液吸收测定二氧化硫的稳定性研究

Study on the Stability of Determining Sulfur Dioxide by Using Methanol Buffer Solution Absorption

本文根据对不同浓度在不同的保存条件下 SO2 的测定的具体数据 ,分析了用甲醛缓冲溶液吸收—盐酸副玫瑰苯胺分光光度法测定 SO2 的稳定性。实验显示中浓度的溶液 ,用玻璃瓶存放 ,在室温下或冰箱内保存 ,均具有很好的稳定性。

Based on the concrete measured data of sulfur dioxide with different concentration in different preserve conditions,this paper analyses the stability of determining sulfur dioxide by using methanol buffer solution absorption and hydrochloric acid subsidiary rosaniline spectroptotography method.Experiment shows that the storage of the solution with medium concentration in glass bottle at room temperature or in refrigerator has excellent stability.
