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 =

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.

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 Kinetics for the Adsorption of Uranyl Ion onto Peat at Different pH Value
Advanced Materials Research, 2010Batch 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.

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

A comparison was made of the linear least-squares method and a nonlinear least-square method of the Langmuir isotherm and pseudo second order kinetic model for the biosorption of methylene blue onto rice husk. The parameters obtained from the linear method and the nonlinear method were different. The error analysis was performed.

Sorption kinetics: Obtaining a pseudo-second order rate equation based on a mass balance approach
Journal of Environmental Chemical Engineering, 2014Abstract Various formulations of pseudo second-order rate equations have been widely used in elucidating the rate constants of a wide variety of sorption systems. In this paper, it is shown that a new formulation can be obtained by making use of the mass balance equation of a single stage batch-type system.
