| Abstract: | Sulfuric acid mist is an important indicator in the monitoring of stationary pollution source flue gas. According to the current national standard method "Determination of Stationary Pollution Source Sulfuric Acid Mist by Ion Chromatography" (HJ 544-2016), when monitoring the sulfuric acid mist in each exhaust gas outlet in the factory, there are often some deviations and fluctuations in monitoring results. Conducted on-site investigation and analysis of its process and principle, it was found that the factors of monitoring mainly include the influence of sulfur dioxide in the flue gas, the deviations in the analysis process and the influence of filter material selection and its pretreatment. And the corresponding correct measures are put forward to improve the accuracy of sulfuric acid mist monitoring data. |
