Using of “pseudo-second-order model” in adsorption
Environmental Science and Pollution Research, 2013A 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.

Separation Science and Technology, 2017
ABSTRACTThe kinetics of adsorption in the batch mode is frequently represented by the Lagergren model or the pseudo second-order model. We assess these models in their ability to represent adsorption by comparing them with the predictions of detailed intra-particle diffusion models and also with a variety of experimental data drawn from the literature.

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 =

Pseudo-second-order model for lead ion sorption from aqueous solutions onto palm kernel fiber
Journal of Hazardous Materials, 2006The 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 ...

Kinetic and Pseudo-Second-Order Modeling of Lead Biosorption onto Pine Cone Powder
Industrial & Engineering Chemistry Research, 2010The sorption of lead(II) onto pine cone powder (PCP) and 0.15 mol/L NaOH treated pine cone powder (PCP 0.15), an abundant agricultural waste from the wood industry, was studied to evaluate the effect of NaOH treatment on the kinetics of lead(II) uptake by performing batch kinetic sorption experiments. Batch biosorption kinetics was performed by varying

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.

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 ...

Kinetic experiments were carried out for the sorption of safranin onto activated carbon particles. The kinetic data were fitted to pseudo-second order model of Ho, Sobkowsk and Czerwinski, Blanchard et al. and Ritchie by linear and non-linear regression methods.

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 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
