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 ...

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 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)

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 ...

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 ...
