Sorption from Solution: A Statistical Thermodynamic Fluctuation Theory

open access: yes, 2023
Given an experimental solid/solution sorption isotherm, how can we gain insight into the underlying sorption mechanism on a molecular basis? Classifying sorption isotherms, for both completely and partially miscible solvent/sorbate systems, has been ...

Isotherms describing physical adsorption of Cr(VI) from aqueous solution using various agricultural wastes as adsorbents

open access: yesCogent Engineering, 2016
Various agricultural wastes such as peels of pea (Pisum sativum) pod, tea (Camellia sinensis), and ginger (Zingiber officinale) and banana (Musa lacatan) waste were used to adsorb Cr(VI) from the aqueous solutions.

Sorption of malachite green (MG) by cassava stem biochar (CSB) kinetic and isotherm studies

open access: yes, 2018
Cassava stem biochar (CSB) was produced by pyrolyzing CS at 500°C for 2 hours at nitrogenenvironment. Proximate and ultimate analyses were conducted on CS and CSB.

A New Model for Predicting Sorption Isotherm of Water in Foods

open access: yes, 2011
A new model for predicting sorption isotherms of type II and III based on the Polanyi theory is proposed. This model allows the prediction of the sorption isotherms at different temperatures from one experimental isotherm.

Equation of the Sorption Isotherm on Zeolite Y Including Heterogeneity of the Sorbent: A Novel Modification

open access: yes, 1993
The complex character of water vapour sorption on zeolite Y has been demonstrated. It has been found that the assumptions of the Dubinin theory of volume filling of micropores (TVFM) are applicable to the description of such water vapour sorption.

Application of Nelson\u27s sorption isotherm to wood composites and overlays

open access: yes, 1999
Equilibrium moisture content (EMC) as a function of relative humidity (RH) was measured in oriented strandboard, particleboard, medium-density fiberboard, hardboard, high pressure laminates, and solid wood.
