Heterogeneous reaction of SO2 on CaCO3 particles:Different impacts of NO2 and acetic acid on the sulfite and sulfate formation
文献摘要：
Despite the heterogeneous reaction of sulfur dioxide(SO2)on mineral dust particles signif-icantly affects the atmospheric environment,the effect of acidic gases on the formation of sulfite and sulfate from this reaction is not particularly clear.In this work,using the in-situ diffuse reflectance infrared Fourier transform spectroscopy(DRIFTS)technique,we employed a mineral dust particle model(CaCO3)combined with NO2 and acetic acid to in-vestigate their effects on the heterogeneous reaction of SO2 on CaCO3 particles.It was found that water vapor can promote the formation of sulfite and simulated radiation can facilitate the oxidation of sulfite to sulfate.The addition of NO2 or acetic acid to the reaction system altered the production of sulfate and sulfite accordingly.There was a synergistic effect be-tween NO2 and SO2 that promoted the oxidation of sulfite to sulfate,and a competitive effect between acetic acid and SO2 that inhibited the formation of sulfite.Moreover,light and wa-ter vapor can also affect the heterogeneous reaction of SO2 with the coexistence of multiple gases.These findings improve our understanding of the effects of organic and inorganic gases and environmental factors on the formation of sulfite and sulfate in heterogeneous reactions.
