Abstract

Mesoporous organosilicates containing an ethylene bridge within the otherwise silicate pore walls and an additional organic functionality extended within the pore showed varying adsorption capacities for mercury and dimethylphenol. Thiol and imidazole functionalized organic-inorganic materials were effective for the adsorption of mercury, whereas the purely siliceous mesoporous MCM-41 was more effective for dimethylphenol adsorption than its organosilicate counterparts.
