Effects of freeze-drying and use of artificial seawater on phosphorus exchange isotherms in brackish water sediments

open access: yesSN Applied Sciences, 2022
This study reports results on the estimated magnitude of changes in P sorption isotherms in clayey mud sediments when performed using (1) freeze-dried instead of fresh sediment samples and (2) artificial sea water (ASW) instead of ambient near-bottom ...

Sorption and Desorption of Vanadate, Arsenate and Chromate by Two Volcanic Soils of Equatorial Africa

open access: yesSoil Systems, 2021
Sorption of oxyanions by soils and mineral surfaces is of interest due to their role as nutrients or pollutants. Volcanic soils are variable charge soils, rich in active forms of aluminum and iron, and capable of sorbing anions.

C–S–H gel densification: The impact of the nanoscale on self-desiccation and sorption isotherms [PDF]

open access: yesCement and Concrete Research, 2018
The relationship between humidity and water content in a hydrating cement paste is largely controlled by the nanostructure of the C-S-H gel. Current hydration models do not describe this nanostructure, thus sorption isotherms and self-desiccation are ...

Zeolite crystal layers coupled to piezoelectric sensors [PDF]

open access: yes, 1991
Microporous zeolite crystals were successfully coupled onto the gold electrodes of quartz crystal microbalances (QCM). A self-assembled monolayer of thiol-alkoxysilane coupling agent on the gold surface was used as the interfacial layer to promote ...

Role of Sorption Isotherms in the Analysis of Coupled Heat and Mass Fluxes in Porous Media [PDF]

open access: yes, 2005
The aim of this work is to show the importance of the sorption isotherms in the study of the heat and mass fluxes in unsaturated porous media. General forms of the heat and mass fluxes are presented in terms of experimentally accessible quantities.
