Electrochemical method to study the environmental behavior of Glyphosate on volcanic soils: Proposal of adsorption-desorption and transport mechanisms
(Elsevier B.V., 2019)
Glyphosate is used extensively worldwide, but current evidence suggests detrimental effects on the environment, pollinators, and human health. Glyphosate adsorption kinetics and adsorption/desorption were studied through ...
Adsorption of Aromatics from Base Oil over Polymeric Resins. Equilibrium and kinetics.
(American Chemical Society, 2015-01)
Adsorption of aromatic molecules from base oil over an acid resin (Amberlyst 15w) was studied, with a focus on reducing the aromatic content to that of a white mineral oil. It was found that the adsorption capacity of the ...
Mixed ad/desorption kinetics unraveled with the equilibrium adsorption isotherm
(Elsevier Science, 2019-09)
Predicting ad/desorption rates at solid/solution interfaces is important for environmental and industrial processes. For non-porous surfaces the adsorption process can be divided in film diffusion and surface reactions. ...
O2 Adsorption on ZIF-8: Temperature Dependence of the Gate-Opening Transition
(American Chemical Society, 2014-11-17)
We present the results of an adsorption isotherm study of O2 on the metal–organic framework ZIF-8. This material undergoes a structural transition (“gate-opening”) as a function of increasing pressure and sorbent loading, ...
Adsorption of alizarin, Eriochrome blue black R, and fluorescein using different iron oxides as adsorbents
(American Chemical Society, 2007-11)
This work presents kinetic and thermodynamic analysis of the adsorption of three dyes: alizarin, eriochrome blue black R, and fluorescein onto goethite, Co-goethite, and magnetite of medium Brunauer-Emmett-Teller surface ...
Study of biosorption of rare earth metals (La, Nd, Eu, Gd) by Sargassum sp. biomass in batch systems: Physicochemical evaluation of kinetics and adsorption models
(2009-12-28)
This work evaluated kinetic and adsorption physicochemical models for the biosorption process of lanthanum, neodymium, europium, and gadolinium by Sargassum sp. in batch systems. The results showed: (a) the pseudo-second ...
Statistical thermodynamics of molecules with multiple adsorption states: application to protein adsorption
(Elsevier, 2013-02)
The statistical thermodynamics of molecules with multiple adsorption states has been studied using a lattice model. The thermodynamic functions calculated for a system characterized by two adsorption states are applied to ...
