摘要
为验证大气中SO2的浓度对气态H2O2自动荧光法监测的影响,设置了SO2与H2O2在自动荧光过氧化氢分析仪中的反应实验;同时,利用SO2和H2O2的反应速率公式进行了模拟计算,模拟计算结果与仪器的监测结果基本相符。证明了在大气SO2浓度较高的情况下,气态SO2对H2O2的自动荧光法测定确实会有显著影响,通过模拟计算的方法可对在线监测的H2O2浓度数据进行校正。
In order to validated the influence of SO2 on automated fluorometric method gaseous H2O2 analyzer, the reaction of SO2 and H2O2 was simulated in a gaseous hydrogen peroxide analyzer in laboratory. The reaction was also evaluated by numerical simulation. The results showed the H2O2 data can be evidently influenced by high SO2 concentration. The evaluation outcome of the numerieal simulation matched well with the laboratory results, which means that the outdoor gaseous hydrogen peroxide monitoring data can be revised by numerical simulation using SO2 concentration.
