Beyond Freundlich and Langmuir: The Ruthven–virial equilibrium isotherm for aqueous-solid adsorption systems

KH Chu, MA Hashim, A Mudhoo, J Debord - Chemical Papers, 2023 - Springer
It is the purpose of this paper to investigate the data fitting attributes of the exponential
integral isotherm, which was first derived by Ruthven in 2004 to describe adsorption at gas …

S-shaped adsorption isotherms modeled by the Frumkin–Fowler–Guggenheim and Hill–de Boer equations

KH Chu, MA Hashim, HN Tran, JC Bollinger - Monatshefte für Chemie …, 2023 - Springer
In this study, we used the Frumkin–Fowler–Guggenheim (FFG) and Hill–de Boer (HDB)
isotherm models to describe previously published S-shaped isotherms involving water …

The Jossens isotherm: A critical look at water contaminant adsorption modeling

BYK Chong, MA Hashim, KH Chu - Separation Science and …, 2024 - Taylor & Francis
The Jossens isotherm is a useful model for describing water contaminant adsorption. This
article critically examines several issues that impede its practical application. Initially, it …

A New Two-Parameter Isotherm for Modeling Adsorptive Removal of Water Contaminants

KH Chu, MA Hashim, J Debord, M Harel… - Journal of …, 2023 - ascelibrary.org
The two-parameter Elovich isotherm is increasingly being used to describe the adsorption of
