A Pseudo-Second Order Kinetic Equation for Sorption Processes
Russian Journal of Physical Chemistry A, 2020The problem of substantiating a pseudo-second order equation in the kinetics of sorption processes is considered. A simple way is presented of transforming the Langmuir kinetic equation written for a process within a limited volume into a polynomial relation in the form of the sum of difference terms of first- and second-order kinetic equations.

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2020
Abstract The empirical pseudo-second order rate equation has become the equation of choice to account for adsorption kinetics at solid/aqueous solution interfaces. However, its validity boundaries still remain faint. Here, they are set on the basis of the predictions of the well-established Langmuir model, cast in terms of the relevant kinetic ...

Abstract A three-layer feed forward neural network was constructed and tested to analyze the second order kinetics of solid–liquid adsorption process. The pseudo second order kinetics of auramine O onto activated carbon was used to train the artificial neural network (ANN) to model the sorption system for various operating conditions.

Dynamic studies and pseudo-second order modeling of copper(II) biosorption onto pine cone powder
Desalination, 2010Abstract The chemical interaction between biosorbent functional groups and metal ion species in solution can slightly be altered by chemical treatment of biosorbent surface. The biosorbent kinetics and mechanism for copper(II) biosorption onto pine cone powder and 0.15 mol dm − 3 NaOH treated pine cone powder were determined during batch kinetics ...

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.

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

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.

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.

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 ...
