TCE adsorption by GAC preloaded with humic substances
ranular activated carbon (GAC) adsorption has been identified by the Safe Drinking Water Act amendments of 1986 as the best available technology for removing synthetic organic contaminants (SOCs) from drinking water supplies.1 GAC is particularly suited for treating water because it effectively removes a wide range of organic compounds and can protect water supplies from such transient occurren...
متن کاملThermodynamics of Adsorption in Porous Materials
Thermodynamic equations are de®eloped for adsorption of multicomponent gas mixtures in microporous adsorbents based on the principles of solution thermodynamics. The con®entional spreading pressure and surface area ®ariables, which describe 2-D films, must be abandoned for adsorption in micropores, in which spreading pressure cannot be measured experimentally or calculated from intermolecular f...
متن کاملDeformation of porous carbons upon adsorption.
N2 and CO2 sorption measurements with in situ dilatometry implemented in a commercial volumetric sorption instrument were performed at 77 and 273 K, respectively. The resolution of the linear deformation was about ±0.2 μm. To separate effects due to microporosity, external surface area and mesopores synthetic porous carbons (xerogels) with different external surface areas and microporosities we...
متن کاملFluorocarbon adsorption in hierarchical porous frameworks.
Metal-organic frameworks comprise an important class of solid-state materials and have potential for many emerging applications such as energy storage, separation, catalysis and bio-medical. Here we report the adsorption behaviour of a series of fluorocarbon derivatives on a set of microporous and hierarchical mesoporous frameworks. The microporous frameworks show a saturation uptake capacity f...
متن کاملPorous silicon functionalization for possible arsenic adsorption
Thiol-functionalized porous silicon (PS) monolayer was evaluated for its possible application in As (III) adsorption. Dimercaptosuccinic acid (DMSA) attached to mesoporous silicon via amide bond linkages was used as a chelate for As (III). Two different aminosilanes namely 3-(aminopropyl) triethoxysilane (APTES) and 3-aminopropyl (diethoxy)-methylsilane (APDEMS) were tested as linkers to evalua...
