Surfactant Adsorption Isotherms: A Review [PDF]

open access: yesACS Omega, 2021
The need to minimize surfactant adsorption on rock surfaces has been a challenge for surfactant-based, chemical-enhanced oil recovery (cEOR) techniques. Modeling of adsorption experimental data is very useful in estimating the extent of adsorption and, hence, optimizing the process.

Review of adsorption isotherms models

open access: yesApplied Water Science
Because of its ease of use, affordability, effectiveness, and environmental friendliness, adsorption phenomenon is a widely used separation technique in wastewater treatment and environmental remediation. In a process known as an adsorption isotherm, the

High-performance liquid chromatography as a technique to measure the competitive adsorption of plasma proteins onto latices [PDF]

open access: yes, 1984
Isotherms of human serum albumin (HSA), human immunoglobulin G (HIgG), and human fibrinogen (HFb) onto a polystyrene (PS)-latex were determined by depletion of protein in the solution, which was either followed by radioactivity measurements or by UV ...

Investigation of isotherms of differential heat-entropy adsorption of carbonyl sulfide in CaA zeolite during gas purification [PDF]

open access: yesE3S Web of Conferences, 2023
The task of this research cycle was to measure adsorption isotherms (а) in the temperature range from 273 to 373 K, based on isotherms measured at different temperatures, to calculate isosteric heats (Qd) and entropies (∆Sd) of adsorption in order to ...

CRAFTED: An exploratory database of simulated adsorption isotherms of metal-organic frameworks [PDF]

open access: yesScientific Data, 2022
Grand Canonical Monte Carlo is an important method for performing molecular-level simulations and assisting the study and development of nanoporous materials for gas capture applications. These simulations are based on the use of force fields and partial

Mathematical modeling of adsorption isotherms of water vapour on polymeric ionites used in agrochemical practice [PDF]

open access: yesE3S Web of Conferences, 2023
Polymeric ion-exchange materials (ionites) are used in agriculture to make substrates for complete and long-term plant nutrition. The main nutrients in bound form are contained on the ion-exchange groups of the ionite. The degree of dissociation of these

A Review on the Adsorption Isotherms and Design Calculations for the Optimization of Adsorbent Mass and Contact Time

open access: yesACS Omega, 2023
Adsorption is a widely used chemical engineering unit operation for the separation and purification of fluid streams. Typical uses of adsorption include the removal of targeted pollutants like antibiotics, dyes, heavy metals, and other small to large ...

Multi-component Adsorption Isotherms: Review and Modeling Studies

open access: yesEnvironmental Processes, 2023
Adsorption is an important phenomenon widely used for the removal of contaminants. Several drinking water contaminants such as arsenic and fluoride, vanadium and chromium, nickel, cadmium and cobalt  are found to coexist in nature as multi-component ...

Adsorption of water on the fine fractions of Finnish tills [PDF]

open access: yesBulletin of the Geological Society of Finland, 1986
This study deals with adsorption of water from the vapour phase on till samples at 25°C. The dry weights were determined after drying the samples in an oven at 105°C.
