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 ...
A model for selective adsorption with a localized adsorption energy
(Elsevier Science BvAmsterdamHolanda, 2010)
Diffusion and adsorption selectivities of hydrocarbons over FCC catalysts
(Elsevier Science Sa, 2007-08)
The adsorption isotherms of hexane, toluene and decane on a commercial FCC catalyst were determined in experiments performed in a CREC Riser Simulator laboratory reactor injecting different volumes of the pure hydrocarbons ...
Electrochemically reduced graphene oxide-based screen-printed electrodes for total tetracycline determination by adsorptive transfer stripping differential pulse voltammetry
(Molecular Diversity Preservation International, 2019-12)
Disposable electrochemically reduced graphene oxide-based (ERGO) screen-printed electrodes (SPE) were developed for the determination of total tetracyclines as a sample screening approach. To this end, a selective ...
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 ...
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 ...
Study on the cross-linked molecularly imprinted poly(methacrylic acid) and poly(acrylic acid) towards selective adsorption of diuron
(2016-03-01)
In the present study new molecularly imprinted adsorbents based on poly(methacrylic acid) and poly(acrylic acid) have been synthesized, characterized and evaluated as selective materials for the adsorption of diuron. ...
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 ...
