Adsorption equilibria of trimethylamine on porous adsorbents.

Studies on adsorption removal of odorous pollutants (acetaldehyde and methyl mercaptan), adsorption of acetaldehyde on porous adsorbents.

Acetaldehyde has recently been added to the list of chemicals in the control law for offensive odor in Japan, and its concentration in the atmosphere is limited by the law to the range of 0.05 to 0.5ppm1). Acetaldehyde is emitted into the atmosphere particularly from the factories producing acetic acid, vinyl acetate, and chloroprene. It is well known that acetaldehyde irritates the mucous memb...

Adsorption of Methylene Blue on magnesium silicate: kinetics, equilibria and comparison with other adsorbents.

Batch adsorption from aqueous solutions in a slightly basic medium of Methylene Blue, up to 2500 mg/L, onto synthetic magnesium silicate (Florisil) of three particle size ranges (mean diameters of 112, 200 and 425 microm) was compared to the corresponding adsorption onto activated carbon and Amberlite XAD-2. The best fit of the kinetic results was achieved by a pseudo second-order equation. The...

Thermodynamic formalism of water uptakes on solid porous adsorbents for adsorption cooling applications

Study of Equilibrium Adsorption of Orthophosphate on Alumina Adsorbents

This work is a part of a comprehensive study on economic re-utilization of a phosphate contaminated industrial water stream in a typical petrochemical plant in the Kingdom of Saudi Arabia. The experimental study is primarily the adsorption of orthophosphate at equilibrium conditions on 28x48 mesh Alcan Alumina AA 400G. A fixed amount of orthophosphate solution containing 10 mg/L of phosphorus i...

Chromatographic Characterization of Adsorption Properties of Carbon and Silica Adsorbents

Adsorption isotherms and specific retention volumes of benzene on MCM41C16 mesoporous silica and F4O porous carbon were determined at different temperatures by employing inverse gas chromatography. The differential isosteric enthalpies, -∆Hads , and entropies, -∆Sads , of adsorption were calculated from the retention time data and compared with the results obtained from the adsorption second vi...
