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 ...
Enrichment of Tropical Peat with Micronutrients for Agricultural Applications: Evaluation of Adsorption and Desorption Processes
(Soc Brasileira Quimica, 2014-01-01)
The objective of this work was to evaluate the adsorption and desorption of micronutrients in tropical peats, from the perspective of potential agricultural applications. Adsorption experiments were performed at different ...
Additional constraints in adsorption-desorption kinetics
(American Physical Society, 2009-02)
In this work, the adsorption-desorption kinetic in the framework of the lattice gas model is analyzed. The transition probabilities are written as an expansion of the occupation configurations. Due to that, the detail ...
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 ...
Determination of the process variables for adsorption and desorption of phosphate from wastewater by selective ion exchangers on magnetic particles
(2015-08-04)
In this study different process variables were evaluated for the adsorption and desorption of phosphate from wastewater by using selective ion exchangers with magnetic particles modi-fied with layered double hydroxides ...
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. ...
Adsorption/desorption study of antibiotic and anti-inflammatory drugs onto bioactive hydroxyapatite nano-rods
(Elsevier Science, 2019-06-23)
The use of high doses of antibacterial and anti-inflammatory drugs for patients with bone diseases, associated to implants or bone filling, can develop adverse effects; and consequently, it promotes to think new strategies ...
Sorption of mercury (II) in Amazon soils from column studies

Percolation Effects on Adsorption-Desorption Hysteresis
(American Chemical Society, 2000-07-29)
In the present work we study how the adsorption−desorption hysteresis loop of a mesoporous-disordered medium represented by a three-dimensional dual site-bond model is affected by percolation for different kinds of site ...
