Menisci interactions during adsorption on mesoporous materials: evaluation of delayed and advanced adsorption
(Springer, 2005-07)
Menisci interactions can strongly affect the development of adsorption processes in mesoporous materials. Phenomena such as delayed and advanced adsorption represent outright manifestations of these interactions then leading ...
Kinetics of Phenol Removal from Aqueous Solution by Adsorption onto Peanut Shell Acid-activated Carbon
(Multi-Science Publishing, 2005-12)
A pseudo-second-order rate equation describing the kinetic adsorption of phenol onto peanut shell acid-activated carbon at different initial concentrations, carbon dosages and particle sizes has been developed. The adsorption ...
Adsorptive properties of silica gel for biodiesel refining
(American Chemical Society, 2008-11)
The refining of biodiesel by adsorption over silica gel was assessed. Silica gel samples were used for the adsorption of glycerol and monoglycerides. Room-temperature isotherms for the adsorption of glycerol were measured ...
Adsorption of dimers on heterogeneous surfaces: Scaling behavior for the adsorption isotherms
(Elsevier Science, 2002-08-15)
The localized monolayer adsorption of homonuclear dimers on heterogeneous surfaces with simple topographies is analyzed by combining theoretical modeling and Monte Carlo (MC) simulations. The heterogeneous surfaces are ...
Adsorption of CO2 on mixed oxides derived from hydrotalcites at several temperatures and high pressures
(Elsevier Science Sa, 2018-01)
The adsorption of CO2 on Co, Fe and Ni mixed oxides derived from a commercial hydrotalcite and calcined at 500 °C was measured at several temperatures and pressures. Two types of experiments were considered in this work. ...
Determining rate coefficients for ion adsorption at the solid/water interface: Better from desorption rate than from adsorption rate
(Royal Society of Chemistry, 2020-04-23)
One of the most common approaches in the adsorption kinetic literature is to compare the fitting performance of several empirical or non-empirical equations (pseudo-first order, pseudo-second order, Elovich, parabolic ...
Semiempirical model for adsorption of polyatomics
(American Chemical Society, 2006-03-04)
Multisite-occupancy adsorption is described by using a new formalism based on the occupation balance approximation (Romá, F.; Ramirez-Pastor, A. J.; Riccardo, J. L. J. Chem. Phys. 2001, 114, 10932). In this framework, the ...
DFT+U study of the electronic structure changes of WO3 monoclinic and hexagonal surfaces upon Cu, Ag, and Au adsorption. Applications for CO adsorption
(Elsevier Science, 2021-12)
A periodic DFT+U study about the adsorption of Cu, Ag, or Au on the monoclinic and hexagonal (001) surface of WO3 is presented. The scope is to elucidate the changes in the electronic structure of these materials upon ...
Analysis of CO<inf>2</inf> adsorption in amine-functionalized porous silicas by molecular simulations
(American Chemical Society, 2015-06-01)
We present the results of a combined experimental-molecular simulations approach concerning the capacity for CO<inf>2</inf> adsorption of aminosilica hybrid products synthesized using supercritical fluids. Two porous ...
Norfloxacin adsorption on montmorillonite and carbon/montmorillonite hybrids: pH effects on the adsorption mechanism, and column assays
(Taylor & Francis, 2020-11-03)
The presence of norfloxacin antibiotic (NFX) in drinking water raises significant scientific concern due to the health and environmental problems that may cause. This study aimed to evaluate the NFX removal: 1) in batch ...
