Capture and Separation of SO2 Traces in Metal–Organic Frameworks via Pre‐Synthetic Pore Environment Tailoring by Methyl Groups

open access: yesAngewandte Chemie, 2021
Herein, we report a pre‐synthetic pore environment design strategy to achieve stable methyl‐functionalized metal–organic frameworks (MOFs) for preferential SO2 binding and thus enhanced low (partial) pressure SO2 adsorption and SO2/CO2 separation.

Fast sulfate formation from oxidation of SO2 by NO2 and HONO observed in Beijing haze

open access: yesNature Communications, 2020
Severe events of wintertime particulate air pollution in Beijing (winter haze) are associated with high relative humidity (RH) and fast production of particulate sulfate from the oxidation of sulfur dioxide (SO2) emitted by coal combustion.

Contaminación atmosférica y calidad del aire en Madrid: Análisis de las concentraciones de SO2, CO, NO2, ozono y PM10 (1980-2003)

open access: yesEstudios Geográficos, 2005
[es] En este artículo analizamos la calidad del aire en Madrid a partir de los límites propuestos por la Directiva europea (1999/30/EC) para el SO2, CO, NO2, ozono y PM10.

High temperature SO2 chemisorption on model systems. Implications for in-plume processes. [PDF]

open access: yes, 2010
Volcanic volatile species are scavenged by silicate ash during transition through eruption plumes. Scavenging may form S, F and Cl salts and acids on ash surfaces, though the mechanisms and controlling variables remain poorly understood.
