English

Subject field(s)
  • Chemistry
  • Nuclear Waste Materials
  • Mining Engineering
  • Water Treatment (Water Supply)
DEF

The surface retention of solid, liquid, or gas molecules or of ions by a solid or liquid, as opposed to absorption, the penetration of substances into the bulk of the solid or liquid.

CONT

Adsorption [refers to a] process of extracting a pollutant by causing it to be attracted to and attached to an adsorbent cleaner.

CONT

The adsorption of radioactive waste relates to the capability of soils, clay, etc., to retain the material and hence prevent it from reaching the biosphere.

OBS

Broadly, adsorption at a solid-liquid interphase may be physical, electro-chemical or chemical. ... Ionic adsorption includes common-ion adsorption to the mineral lattice, and ion-exchange between the surface lattice-charges of solid and the ions in solution (the surface-modifying effects utilised in the flotation process).

French

Domaine(s)
  • Chimie
  • Déchets nucléaires
  • Génie minier
  • Traitement des eaux
DEF

[...] fixation superficielle quasi réversible d'une substance liquide ou gazeuse (substance adsorbée) à la surface d'un support solide (support adsorbant).

OBS

Il s'agit donc d'un phénomène de surface [...] par opposition à l'absorption qui [...] se déroule dans la profondeur de la masse solide [...]

PHR

Adsorption sur le charbon actif.

PHR

Adsorption spécifique.

PHR

Entraîner par adsorption (les radionucléides).

Spanish

Campo(s) temático(s)
  • Química
  • Desechos nucleares
  • Ingeniería de minas
  • Tratamiento del agua
DEF

Absorción de un gas o un líquido por la parte superficial de un cuerpo sólido; por ejemplo, de ciertos gases por el carbón, circunstancia que se aprovecha en las caretas de defensa contra los gases tóxicos.

Record 2 2005-02-28

English

Subject field(s)
  • Atmospheric Physics
DEF

The adhesion of a thin film of liquid or gas onto a solid substance.

OBS

The solid does not chemically combine with the adsorbed substance.

OBS

Adsorption ... must be distinguished from absorption, the filling of pores in a solid.

French

Domaine(s)
  • Physique de l'atmosphère
DEF

Rétention à la surface d'un solide ou de grosses molécules (matière organique) de molécules gazeuses, liquides, dissoutes, d'ions ou de particules en suspension.

OBS

Ne pas confondre avec absorption.

Spanish

Campo(s) temático(s)
  • Física de la atmósfera
DEF

Adherencia de los átomos, iones o moléculas de un fluido a la superficie de otra sustancia, denominada adsorbente. Los sistemas más conocidos y utilizados son gas/sólido y líquido/sólido.

Record 3 2004-11-17

English

Subject field(s)
  • Oil Refining
DEF

Separation according to size or type making use of the difference in adhesion to porous material (gas solid and liquid solid systems).

DEF

The adhesion of a thin film of a gas or liquid to the surface of a solid.

OBS

Liquid hydrocarbons are recovered from natural gas by passing the gas through activated charcoal, silica gel, or other solids, which extract the heavier hydrocarbons, which are then collected and recondensed.

French

Domaine(s)
  • Raffinage du pétrole
CONT

L'adsorption est utilisée dans le raffinage du pétrole, pour améliorer la couleur des huiles et en extraire les composants asphaltiques ou résineux indésirables.

Spanish

Campo(s) temático(s)
  • Refinación del petróleo
CONT

La separación de alquitrán de los gases se efectúa por adsorción y las tierras adsorbentes se usan en las refinerías para purificar aceites, gasolina y otros productos derivados del petróleo.
