Competitive Adsorption of Phenols on GAC. I: Adsorption Equilibrium

Journal of Environmental Engineering, 1993
The impact of the presence of molecular oxygen on multicomponent adsorption is evaluated in this study. Adsorption equilibria for binary mixtures of phenol/o‐cresol and ternary mixtures of phenol/o‐cresol/3‐ethylphenol on granular activated carbon (GAC) are determined at 23°C using three different initial‐concentration combinations.

Competitive Protein Adsorption—Multilayer Adsorption and Surface Induced Protein Aggregation

Langmuir, 2009
In this study, competitive adsorption of albumin and IgG (immunoglobulin G) from human serum solutions and protein mixtures onto polymer surfaces is studied by means of radioactive labeling. By using two different radiolabels (125I and 131I), albumin and IgG adsorption to polymer surfaces is monitored simultaneously and the influence from the presence ...

Modeling of levofloxacin adsorption to goethite and the competition with phosphate

Chemosphere, 2014
Interaction between various compounds in natural systems may influence the adsorption of these species and their environmental fate. In this work, we studied the interactions between a widely used antibiotic levofloxacin (LEV) and phosphate at the surface of goethite (α-FeOOH), which was important to better understand the competitive adsorption of ...

Competitive Adsorption as a Route to Area-Selective Deposition

ACS Applied Materials & Interfaces, 2020
In this work, we have explored the use of a third species during chemical vapor deposition (CVD) to direct thin-film growth to occur exclusively on one surface in the presence of another. Using a combination of density functional theory (DFT) calculations and experiments, including in situ surface analysis, we have examined the use of 4-octyne as a ...

Competition between self-assembly and surface adsorption

The Journal of Chemical Physics, 2009
We investigate a minimal equilibrium polymerization model for the competition between self-assembly on a boundary and in solution that arises when an assembling system is in the presence of an adsorbing interface. Adsorption generally occurs upon cooling, but assembly (equilibrium polymerization) may arise either upon cooling or heating. Both cases are

Competitive adsorption behavior of heavy metals on kaolinite

Journal of Colloid and Interface Science, 2005
Polluted and contaminated soils can often contain more than one heavy metal species. It is possible that the behavior of a particular metal species in a soil system will be affected by the presence of other metals. In this study we have investigated the adsorption of Cd(II), Cu(II), Pb(II), and Zn(II) onto kaolinite in single- and multi-element systems

Competitive Protein Adsorption in Isocratic Anion Exchange Chromatography

Journal of Chromatography A, 2023
Protein chromatography is the dominant method of purification of biopharmaceuticals. Although all practical chromatography involves competitive absorption and separation of M. species, competitive protein absorption has remained inadequately understood.

Nanoconfined competitive adsorption and wettability transition

Journal of Colloid and Interface Science
Adsorption-driven wettability transitions are fundamental to understanding fluid-solid interfacial phenomena and their impacts on diverse processes in nature and industry. In systems with multiple fluid species, competitive adsorption introduces additional complexity by altering interfacial energy and fluid behavior.

Competitive and cooperative adsorption of arsenate and citrate on goethite

Journal of Environmental Sciences, 2009
The fate of arsenic in natural environments is influenced by adsorption onto metal (hydr)oxides. The extent of arsenic adsorption is strongly affected by coexisting dissolved natural organic acids. Recently, some studies reported that there existed competitive adsorption between arsenate and citrate on goethite. Humic acid is known to interact strongly

Competitive adsorption of surfactants at air/water interfaces

Journal of Colloid and Interface Science, 2003
The zeta potential of an air bubble suspended in an aqueous solution of mixed fluorocarbon and hydrocarbon anionic surfactants is studied over a wide range of concentrations and mixture compositions. The zeta potential is related to surfactant ion adsorption.
