Pseudo-second-order model for lead ion sorption from aqueous solutions onto palm kernel fiber

Journal of Hazardous Materials, 2006
The sorption of lead ion onto palm kernel fiber was studied by performing batch kinetic sorption experiments. The batch sorption model, based on a pseudo-second-order mechanism, was applied to predict the rate constant of sorption, the equilibrium capacity and the initial sorption rate with the effects of the initial solution pH and fiber dose ...

Using of “pseudo-second-order model” in adsorption

Environmental Science and Pollution Research, 2013
A research paper's contribution exists not only in its originality and creativity but also in its continuity and development for research that follows. However, the author easily ignores it. Citation error and quotation error occurred very frequently in a scientific paper.

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 ...

The real pseudo-second-order rate equation

Industrial Crops and Products, 2014
This pseudo second-order model is not correct. In fact, the seudo-second-order kinetic expression for the adsorption sysems of divalent metal ions using sphagnum moss peat has been resented by Ho in 1995 (Ho, 1995). The pseudo-second-order inetic model has a non-linear form qt = qe kt/1 + qekt and four linar forms such as t/qt = 1/kqe + (1/qe)t, 1/qt =

On the use of linearized pseudo-second-order kinetic equations for modeling adsorption systems

Desalination, 2010
Abstract Simulated pseudo-second-order kinetic adsorption data were analyzed by different methods of least-squares regression. The methods used were non-linear regression and four linearized forms of the pseudo-second-order equation. The simulated data were compromised with three different homoskedastic and heteroskedastic error distributions. In the

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

New insights into pseudo-second-order kinetic equation for adsorption

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2008
Abstract This study looked into the theoretical basis of the most commonly used pseudo-second-order kinetic equation for adsorption. It was demonstrated that the pseudo-second-order kinetic equation for adsorption indeed is in line with the universal rate law for a chemical reaction, while the same principle can also be applied to the pseudo-first ...

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.

Erroneous Application of Pseudo-Second-Order Adsorption Kinetics Model: Ignored Assumptions and Spurious Correlations

Industrial & Engineering Chemistry Research, 2018
In this research note, we revisit the pseudo-second-order model for adsorption kinetics, its assumptions, and its application to simulated, random, and published data.
