Competitive Adsorption of Phosphate and Oxalate by Aluminum Oxides
Soil Science Society of America Journal, 1991Abstract The aim of this work was to study: (i) the competitive adsorption of phosphate (P) and oxalate (OX) anions on an Al oxide as influenced by pH and order of anion addition; and (ii) the adsorption of P on and the desorption of OX from an Al precipitation product [Al(OH)

Macromolecules, 1992
Kinetics and isotherms of individual and binary mixture of various monodisperse polystyrenes on three porous silica surfaces were investigated in cyclohexane and CCl 4 as a function of the ratio of the pore size to twice the radius of gyration of a PS chain in a bulk ...

Langmuir, 2013
The adsorption of members of the homologous series of alkyl trimethylammonium bromides (C(n)TAB) is studied at water/alkane interfaces by drop profile analysis tensiometry. The results are discussed in terms of a competitive adsorption process of alkane and surfactant molecules. A thermodynamic model, derived originally for the adsorption of surfactant

Adsorption and Competitive Adsorption on Zeolites of Nitrophenol Compounds Present in Wastewater
Industrial & Engineering Chemistry Research, 2008This work investigates the removal of various nitrophenolic compounds (ortho-nitrophenol (ONP), para-nitrophenol (PNP), meta-nitrophenol (MNP), and 2,4-dinitrophenol (2,4-DNP)) from aqueous solution using hydrophobic FAU zeolites. The adsorption equilibrium of nitrophenols from aqueous solutions by FAU can be well-described using the Fowler−Guggenheim ...

Competitive Adsorption of Nonionic Surfactant and Nonionic Polymer on Silica
Langmuir, 2007Competitive adsorption of the nonionic polymer poly(ethylene oxide) (PEO) and the nonionic surfactant of the type poly(ethylene oxide) alkyl ether from aqueous solutions on a silica surface is examined. From one-component solutions, both species readily adsorb onto silica and, in the bulk of mixed (two-component) solutions, polymer-surfactant complexes

Competitive adsorption of polymers on metal nanoparticles
Surface Science, 2007We investigate the effect of system properties and adsorption sequence on competitive adsorption of poly(methyl methacrylate) (PMMA) and polystyrene (PS) on narrowly polydispersed cobalt (Co) nanoparticles (D ∼ 27 nm). The adsorbed layer composition is studied using thermo-gravimetric analysis (TGA).

The effect of competitive adsorption on the rate of diffusion
Journal of Applied Polymer Science, 1976AbstractEvidence is presented that the apparent diffusion coefficient of one penetrant can be increased by competition from another penetrant for the same adsorption sites in polyester. The competition is governed by the relative diffusivities of the penetrants and their affinities for the adsorption sites.

Adsorption of sticky hard spheres: relevance to protein competitive adsorption
Journal of the Chemical Society, Faraday Transactions, 1992The sticky hard sphere model provides a simple analytic theory of competitive adsorption which may be relevant to the modelling of protein competitive adsorption. Equilibrium monolayer compositions are calculated here for binary mixtures of equal sized molecules as a function of adsorbate concentration and difference in ‘stickiness’ at the adsorbent ...
