Competitive plasma protein adsorption onto fluorinated polyimide surfaces

Journal of Biomedical Materials Research Part A, 2003
AbstractA series of fluorinated polyimides cured at different temperatures was prepared, and plasma protein adsorption and platelet adhesion onto the polyimide films were evaluated in vitro using scanning electron microscopy, a micro‐bicinchoninic acid protein assay, and a gold–colloid‐labeled immunoassay.

Competitive adsorption from mixed nonionic surfactant/protein solutions

Journal of Colloid and Interface Science, 2004
A thermodynamic model is derived which is suitable to describe adsorption from a mixed protein/surfactant solution. The comparison with experimental data for HSA mixed with the nonionic surfactant decyl dimethyl phosphine oxide shows good agreement. Some model calculations are discussed in terms of the competitive character of the process of adsorption

Competitive Adsorption of Cd and Dyes to Kaolinite

Clays and Clay Minerals, 2006
AbstractThe competitive adsorption to kaolinite between Cd(II) and four polyaromatic dyes (9-aminoacridine, 3,6-diaminoacridine, azure A and safranin O) was studied in 5 mM KNO3 at 25°C. Under these conditions, Cd adsorbs to the silica face of kaolinite between about pH 4 and 6.5, but at higher pH, adsorbed Cd is progressively relocated to the crystal ...

COMPETITIVE ADSORPTION DURING SOLUTE TRANSPORT IN SOILS

Soil Science, 1983
Experimental evidence from the literature is presented to demonstrate that adsorption of chemical substances in soils and related materials is significantly influenced by competition from other adsorbing chemicals. Both organic and inorganic ions are capable of competing for adsorption sites on soils.

Competitive ion-exchange adsorption of proteins: Competitive isotherms with controlled competitor concentration

Journal of Chromatography A, 2005
The competitive adsorption processes inevitably present in chromatographic separations of complex mixtures have not been extensively studied. This is partly due to the difficulty of measuring true competitive isotherms, in which all system parameters (including competitor concentrations) are held constant.

Non-competitive and competitive adsorption of Cd2+, Ni2+, and Cu2+ by biogenic vaterite

Science of The Total Environment, 2019
Ubiquitous 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 ...

Competitive activated carbon adsorption of phenolic compounds

Environmental Pollution Series B, Chemical and Physical, 1986
Abstract Competitive adsorption, by activated carbon, of phenolic compounds from 2- and 3-solute mixtures was studied. Phenols with 2 or 3 chlorine substituents (2,4-dichlorophenol and 2,4,6-trichlorophenol) were strongly adsorbable and adsorbed preferentially to 2-chlorophenol, phenol and m-cresol. Data generally fit Freundlich adsorption isotherms.
