Electrolyte adsorption on heterogeneous surfaces: adsorption models
Journal of Colloid and Interface Science, 1986Several heterogeneous electrolyte adsorption models are derived. The underlying assumptions for these models and their applicability are discussed. It is shown that the pristine point of zero charge (PPZC) may well be a function of the degree of surface heterogeneity.

Comptes Rendus de l'Académie des Sciences - Series IV - Physics, 1992
Because of both their practical importance and their fundamental properties [1], polymers at interfaces have been under constant study. In this paper, we will consider the adsorbtion of linear chains on flat surfaces. Theoretical interest in this question was renewed recently by the introduction of scaling methods by de Gennes [2], Pincus [3], Binder ...

Adsorption volume and absolute adsorption: 2. Adsorption from liquid phase
Colloid Journal, 2007A critical analysis of the isotherms of excess and absolute adsorption, as well as the adsorption space performed in the first part [1] is continued; however, as applied to the equilibrium physical adsorption from the liquid phase. The correct method is proposed for evaluating the adsorption volume of solid adsorbents with an arbitrary structure by the

Adsorptive Separations and Adsorptive Reactors
1993The importance of adsorptive processes has increased over the last decades with applications in chemical industry and in areas related with environment, energy and biotechnology; this renewed interest in adsorption was accompanied by the publication of several books [1–5].

Adsorption volume and absolute adsorption: 1. Adsorption from a gaseous phase
Colloid Journal, 2007Important concepts of adsorption science, such as excess and absolute adsorption isotherms and adsorption space volume, are critically analyzed and their status is discussed. An adequate method is proposed for evaluating the adsorption volume of solid adsorbents having arbitrary structures from excess adsorption isotherms.

Sulfate Adsorption on Goethite
Journal of Colloid and Interface Science, 1999Recent spectroscopic work has suggested that only one surface species of sulfate is dominant on hematite. Sulfate is therefore a very suitable anion to test and develop adsorption models for variable charge minerals. We have studied sulfate adsorption on goethite covering a large range of sulfate concentrations, surface coverages, pH values, and ...

The adsorption isotherm and thermodynamics of adsorption equilibrium
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19691. Four previously proposed methods of calculating the differential entropies and heats of adsorption on the basis of one adsorption isotherm were compared, and their possibilities and limits of applicability were discussed. 2. A new thermodynamic method of approximate calculation of the differential heats and entropies of adsorption ...

Adsorption on a random configuration of adsorptive heterogeneities
Journal of Colloid and Interface Science, 1978A monolayer model for gas adsorption on a random topology of heterogeneities is investigated using a numerical regularization method to obtain adsorptive energy distributions. The numerical method is applicable to both patchwise and random topology models of heterogeneity but may not be able to distinguish between them. The stability of the solution is
