Implications of apparent pseudo-second-order adsorption kinetics onto cellulosic materials: A review [PDF]

open access: yesBioResources, 2019
The pseudo-second-order (PSO) kinetic model has become among the most popular ways to fit rate data for adsorption of metal ions, dyes, and other compounds from aqueous solution onto cellulose-based materials.

A Revised Pseudo-Second Order Kinetic Model for Adsorption, Sensitive to Changes in Sorbate and Sorbent Concentrations [PDF]

open access: yes, 2020
Much contemporary research considers the development of novel sorbents for the removal of toxic contaminants. Whilst these studies often include experimental adsorption kinetics, modelling is normally limited to application of the pseudo-second order (PSO) rate equation, which provides no sensitivity towards changes in ...

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

open access: yesLangmuir
The 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.

Pseudo-Second-Order Calcium-Mediated Cryptosporidium parvum Oocyst Attachment to Environmental Biofilms. [PDF]

open access: yesAppl Environ Microbiol, 2017
ABSTRACT Cryptosporidium parvum oocysts are able to infect a wide range of mammals, including humans, via fecal-oral transmission. The remobilization of biofilm-associated C. parvum oocysts back into the water column by biofilm sloughing or bulk erosion poses a threat to public health and may ...

Two new linearized equations derived from the pseudo-second-order kinetic model

open access: yesDesalination and Water Treatment, 2023
There are six different linearized models of the pseudo-second-order kinetic model found in the lit-erature. The pseudo-second-order kinetic model's linearized model count was expanded to eight in this study by deriving two newly linearized models. This study used experimental data from the lit-erature for creating plots of these two new models. In the

A Revised Pseudo-Second-Order Kinetic Model for Adsorption, Sensitive to Changes in Adsorbate and Adsorbent Concentrations

open access: yesLangmuir, 2021
The development of new adsorbent materials for the removal of toxic contaminants from drinking water is crucial toward achieving the United Nations Sustainable Development Goal 6 (clean water and sanitation). The characterization of these materials includes fitting models of adsorption kinetics to experimental data, most commonly the pseudo-second ...

Modeling of sorption kinetics: the pseudo-second order equation and the sorbate intraparticle diffusivity [PDF]

open access: yesAdsorption, 2013
The applicability of the pseudo-second order equation (PSOE) has been explained on the ground of the model assuming that the overall sorption rate is limited by the rate of sorbate diffusion in the pores of sorbent (intraparticle diffusion model). Mathematical expressions have been proposed in order to describe the dependence of the pseudo-second order

Discrete Weighted Pseudo Asymptotic Periodicity of Second Order Difference Equations

open access: yesDiscrete Dynamics in Nature and Society, 2014
We define the concept of discrete weighted pseudo-S-asymptotically periodic function and prove some basic results including composition theorem. We investigate the existence, and uniqueness of discrete weighted pseudo-S-asymptotically periodic solution ...

WELL-POSEDNESS OF THE CAUCHY PROBLEM FOR p-EVOLUTION SYSTEMS OF PSEUDO-DIFFERENTIAL OPERATORS [PDF]

open access: yes, 2013
We study p-evolution pseudo-differential systems of the first order with coefficients in (t,x) and real characteristics. We find sufficient conditions for the well-posedness of the Cauchy problem in H∞.

Studies on the Adsorption Behavior of 152+154Eu (III) on Synthesized Graphene Oxide

open access: yesJournal of Scientific Research in Science, 2020
Graphene oxide (GO) Samples are locally synthesized for use in sorption and radionuclides removal studies of 152+154Eu (III). The samples were characterized by FT-IR, X-ray diffraction (XRD) and electron scanning microscopy (SEM). These samples are used
