POSITIVE ADSORPTION [4 records]

Record 1 2011-04-04

English

Subject field(s)
  • Chemistry
DEF

The depletion of one or more components in an interfacial layer.

CONT

An excess of solute at the surface, as measured by +μ, can be termed positive adsorption to distinguish it from an excess of solvent at the surface(-μ), or negative adsorption.

French

Domaine(s)
  • Chimie
DEF

L'épuisement de l'un ou de plusieurs composants d'une couche interfaciale.

Record 2 2011-04-04

English

Subject field(s)
  • Chemistry
CONT

An excess of solute at the surface, as measured by +μ, can be termed positive adsorption to distinguish it from an excess of solvent at the surface(-μ), or negative adsorption. According to Gibbs equation, positive adsorption and the lowering of surface tension always appear simultaneously.

Record 3 1996-10-11

English

Subject field(s)
  • Chemistry
CONT

If adsorption equilibrium and mutual saturation of the phases is not achieved instantly, it is possible to distinguish the initial spreading tension.. from the final spreading tension... when equilibrium has been reached. In the case in which... [the initial spreading tension] is positive, while... [the final spreading tension] is negative, the system is said to exhibit autophobicity.

French

Domaine(s)
  • Chimie
CONT

Si l'équilibre d'adsorption et la saturation mutuelle des phases n'est pas atteint instantanément, il est possible de distinguer entre la tension initiale de mouillage, [...] et la tension finale de mouillage [...] atteinte à l'équilibre. Dans les cas où la valeur [...] [de la tension initiale de mouillage] est positive alors que [...] [la valeur de la tension finale de mouillage] est négative, on dit que le système présente de l'autophobicité.

Record 4 1996-10-11

English

Subject field(s)
  • Chemistry
DEF

The surface excess amount or Gibbs adsorption of component i, ni, superscript sigma, which may be positive or negative, is defined as the excess of the amount of this component actually present in the system over that present in a reference system of the same volume as the real system and in which the bulk concentrations in the two phases remain uniform up to the Gibbs dividing surface.

French

Domaine(s)
  • Chimie
DEF

La quantité d'excès en surface ou l'adsorption de Gibbs de la composante i, ni, exposant sigma, qui peut être positive ou négative, est définie comme l'excès de la quantité de cette composante présente dans le système par rapport à celle qui est présente dans un système de référence dont le volume est identique à celui du système réel et dans lequel les concentrations dans la masse de la solution de chacune des deux phases demeurent uniformes jusqu'à la surface de division de Gibbs.
