The real pseudo-second-order rate equation
Industrial Crops and Products, 2014This 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 =

Characteristics of pseudo-second-order kinetic model for liquid-phase adsorption: A mini-review
Chemical Engineering Journal, 2009Abstract 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.

On the use of linearized pseudo-second-order kinetic equations for modeling adsorption systems
Desalination, 2010Abstract 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

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 ...

New insights into pseudo-second-order kinetic equation for adsorption
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2008Abstract 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 ...

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, 2010A 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, 2020Abstract 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.

Abstract The kinetics of adsorption for Langmuir and Freundlich isotherms has been explored theoretically on the basis of Statistical Rate Theory (SRT). The Modified Pseudo-First-Order (MPFO) and Pseudo-First-Order (PFO) models were derived from Freundlich isotherm on the basis of Statistical Rate Theory at c 0 ≫ c e and at close to ...
