Thermodynamics of adsorption of surfactants at solid-liquid interface

Adsorption of surfactants at interfaces is detenIlined by a number of forces involving electrostatic attraction, covalent bonding, hydrogen bonding, hydrophobic bonding and solvation and desolvation of various species. The extent and type of forces involved vary depending on the adsorbate and the adsorbent and also the composition and other characteristics of the solvent and dissolved component...

Adsorption of Proteins at Solid-Liquid Interfaces

This paper concisely rev iews the general principles underlying protein adsorption from aqueous so lution onto a solid surface. The discussion includes the various stages of the adsorption process, i. e., transport o f the protein molecules towards the su rface, the absorbed amount under equilibrium conditions, desorption andreadsorption. Among the interactions that determine the overall protei...

DNA adsorption at liquid/solid interfaces.

DNA adsorption on solid or liquid surfaces is a topic of broad fundamental and applied interest. Here, we study by X-ray reflectivity the adsorption of monodisperse double-stranded DNA molecules on a positively charged surface, obtained through chemical grafting of a homogeneous organic monomolecular layer of N-(2-aminoethyl) dodecanamide on an oxide-free monocrystalline Si(111) wafer. The adso...

thermodynamics ofcu2+adsorption on soilhumin

the adsorption thermodynamic characteristic of cu2+ from aqueous solution onto humin andalso humic acid from a typical black soil in northeast china were examined at three different temperatures(298, 318 and 338 k) by batch isotherm experiments. results showed that humin was structurally differentfrom humic acid. the increase of temperature had a positive effect on the adsorption process. freun...
