Adsorption of reactive dye on seawater-neutralised bauxite refinery residue
(2013-02-11)
This investigation has demonstrated the need for thermal treatment of seawater neutralised red mud (SWRM) in order to obtain reasonable adsorption of Reactive Blue dye 19 (RB 19). Thermal treatment results in a greater ...

Monte Carlo simulations of the adsorption of potassium on a Cu(111) surface
(AMER INST PHYSICS, 1998)
Monte Carlo simulations of the adsorption of potassium on a Cu(111) surface at 80 K and coverages going from theta=0.13 ' to theta=0.26 monolayer are reported. The particles interact through an adsorbate-substrate potential ...
Water vapor adsorption performance of Ag and ni modified 5A zeolite
(Elsevier, 2018-07-15)
In this work, Ag and Ni metals incorporation effect on the water adsorption and physicochemical properties of 5A zeolite was studied. For that, Ag/5A and Ni/5A zeolites with different amounts of metal (4, 10 and 20 wt%) ...
Model size effects on calculated electronic and bonding properties of adsorption sites in zeolites

Adsorption and characterization of MCPA on DDTMA- and raw-montmorillonite: Surface sites involved
(Taylor & Francis, 2016-04)
The 4-chloro-2-methylphenoxy acid (MCPA) is an herbicide widely used in agriculture, which generates a great concern about contamination of surface water and serious consequences for human health and the environment. In ...
Equilibrium mono- and multicomponent adsorption models: From homogeneous ideal to heterogeneous non-ideal binding
(Elsevier Science, 2020-06)
Aqueous sorption processes play an important role in, for example, pollutant binding to natural nanoparticles, colloid stability, separation and enrichment of components and remediation processes. In this article, which ...
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 kinetic, thermodynamic and desorption studies of phosphate onto hydrous niobium oxide prepared by reverse microemulsion method
(SPRINGER, 2010)
A type of Nb(2)O(5)center dot 3H(2)O was synthesized and its phosphate removal potential was investigated in this study. The kinetic study, adsorption isotherm, pH effect, thermodynamic study and desorption were examined ...
