Functionalized organosilicate materials for irritant gas removal

► Under dry conditions, organosilicates remove more ammonia than the carbon material. ► Isocyanate functional groups improve ammonia removal under humid conditions. ► Amine functional groups improve cyanogen chloride removal. ► Sulfur dioxide removal is enhanced in materials with amine functional groups. ► Octane adsorption by all sorbents is negatively impacted by increased humidity.
