Competitive Protein Adsorption in Isocratic Anion Exchange Chromatography
Journal of Chromatography A, 2023Protein 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.

Competitive Adsorption as a Route to Area-Selective Deposition
ACS Applied Materials & Interfaces, 2020In 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 ...

Modeling of levofloxacin adsorption to goethite and the competition with phosphate
Chemosphere, 2014Interaction 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 ...

A mathematical model for competitive adsorptions
Separation and Purification Technology, 2015Abstract Adsorption is widely applied in separation and purification of gas mixtures and liquids. A competitive multicomponent multilayer kinetic model is derived for adsorption on solid surfaces, without an artificial distinction between chemisorption and physisorption. The adsorption isotherm was derived based on the kinetic model.

Competitive adsorption of phosphate and phosphonates onto goethite
Water Research, 2006Phosphate and phosphonates are both strongly adsorbed onto mineral surfaces and their removal during wastewater treatment is mainly due to adsorptive processes. We have conducted experiments to study the mutual influence of phosphate and six different phosphonates on each other in buffered medium at pH 7.2.

The evidence for the competitive adsorption of inhibitors
Corrosion Science, 1993Abstract The effects of two thioamide derivatives on the corrosion rate of mild steel in 2 M H 2 SO 4 has been investigated at various concentrations of dimethylformamide (DMF) at 30°C. The thioamides under consideration inhibited the corrosion rate significantly.

Competitive Adsorption on Wollastonite: An Atomistic Simulation Approach
The Journal of Physical Chemistry B, 2005Atomistic simulation techniques are used to simulate surface structure and adsorption behavior of scarcely floatable wollastonite mineral in the presence of molecular and dissociated water, methanoic acid, and methylamine. The latter two additives represent the two widely used collector head-group molecules. The static energy minimization code METADISE

Competitive Adsorption of Acetic Acid and Water on Kaolinite
The Journal of Physical Chemistry A, 2016Mineral dust is prevalent in the atmosphere as a result of emissions from natural and anthropogenic sources. As mineral dust particles undergo long-distance transport, they are exposed to trace gases and water vapor. We have characterized the interactions of acetic acid on kaolinite using diffuse reflectance infrared Fourier transform spectroscopy and ...

Competitive adsorption of surfactants at air/water interfaces
Journal of Colloid and Interface Science, 2003The 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.

Non-competitive and competitive adsorption of Cd2+, Ni2+, and Cu2+ by biogenic vaterite
Science of The Total Environment, 2019Ubiquitous bio-minerals exert significant effects on the migration and transformation of metal ions in the environment, however, research into the adsorption of heavy metals by biogenic vaterite (BV) has rarely been reported. The aim of our research was to evaluate the removal effects of Cd2+, Ni2+, and Cu2+ in single and multi-metal ion aqueous ...
