Characteristics of pseudo-second-order kinetic model for liquid-phase adsorption: A mini-review

Chemical Engineering Journal, 2009
Abstract Since the introduction of pseudo-second-order (PSO) model for the description of adsorption kinetics in 1999, it has been widely applied in liquid-phase adsorption systems. An approaching equilibrium factor (Rw) was defined and deduced from the PSO model in this work.

Modeling pseudo-second-order kinetics of orange peel-paracetamol adsorption process using artificial neural network

Chemometrics and Intelligent Laboratory Systems, 2020
Abstract In this work, an artificial neural network (ANN) was developed to model the Pseudo- Second Order (PSO) kinetics of orange peel-paracetamol adsorption process. The orange peel used for the adsorption process was prepared, activated, and characterized using Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR ...

Pseudo second-order Jahn-Teller effects and symmetry considerations in transition metal polyhydride complexes

Inorganica Chimica Acta, 1997
Abstract Pseudo second-order Jahn-Teller distortions are proposed to explain why the equatorial hydride ligands in a series of cyclopentadienyl metal polyhydrides (Cp ∗ ReH 6 , Cp ∗ OsH 5 , Cp ∗ IrH 4 ) bend away from the Cp ring at such large angles. Restricted Hartree-Fuck (RHF) geometry optimizations on models of these complexes where the Cp* ring

A Pseudo Second-Order Kinetic Expression for Dissolution Kinetic Profiles of Solids in Solutions

Industrial & Engineering Chemistry Research, 2010
A pseudo second-order kinetic expression was presented to explain the dissolution kinetics of solids in solution. The kinetic constant, initial dissolution rate, and theoretical saturation concentration according to pseudo second-order kinetic expression was defined.

Adsorption kinetics models in clay systems. The critical analysis of pseudo-second order mechanism

Applied Clay Science, 2020
Abstract The research topics involving adsorption kinetics of chemical substances on clays and related materials include hundreds of papers over the last decades. In many of them, it is concluded that the adsorption is governed by the so-called pseudo-second order (PSO) mechanism.

Biosorption of Cr(VI) onto marine Aspergillus niger: experimental studies and pseudo-second order kinetics

World Journal of Microbiology and Biotechnology, 2009
The removal of hexavalent chromium from aqueous solution was studied in batch experiments using dead biomass of three different species of marine Aspergillus after alkali treatment. All the cultures exhibited potential to remove Cr(VI), out of which, Aspergillus niger was found to be the most promising one.

Pseudo-Second-Order Kinetic Equation for Describing the Effect of Sorbent and Sorbate Concentrations

Langmuir
The sorbent concentration (Cs) effect and sorbate initial concentration (C0) effect are common phenomena observed in the study of adsorption kinetics at solid-liquid interfaces. That is, adsorption rate constants simulated with classical kinetic equations, such as the pseudo-second-order (PSO) model, for a given system vary with Cs and C0.

Pseudo-Second-Order Kinetics for the Adsorption of Uranyl Ion onto Peat at Different pH Value

Advanced Materials Research, 2010
Batch tests were used to investigate the effects of pH and contact time on the adsorption capability of peat. The results indicate that adsorption of uranyl ions on peat increase with increasing pH from 1 to 5. However it takes longer contact time to reach the adsorption equilibrium with increase of pH from 1 to 5.
