to attract and bind (molecules of a substance in a fluid) so as to form a thin layer on the surface, by non-electrostatic forces; to bind by adsorption. Distinguished from absorb, in which the foreign substance penetrates the body of the absorbing material.
to form a thin layer of molecules of a substance on the surface of a solid or liquid.
To collect (a gas, etc.) in condensed form on a surface.
The physio-chemical phenomenon involved to attract and hold a gas, vapour, or liquid on the surface of a solid, particularly on a finely divided material.
Molecules of gas, liquid, or dissolved solids that adhere or "stick" to the surfaces they come in contact with. Some chemicals adsorb strongly to soil particles. This differs from absorb: "to take up or make part of the existing whole," like a sponge absorbs (sucks up) water.
Attachment of a substance to the surface of a material.
accumulate (liquids or gases) on the surface
adhesion of an extremely thin layer of liquid molecules to the surface of a solid with which they are in contact.
Collection of gas or liquid molecules on the surface of another material. For sampling of most organic vapors, activated charcoal is a good absorbant.
Describes what happens when a molecule from a fluid phase (gas or liquid) lands on the surface of a solid and stays, if only for a short while. Adsorb is different from absorb (which see).
To take up and hold (a gas, liquid, or dissolved substance) in a thin layer of molecules on the surface of a solid substance.
To collect a substance on a surface; for example, protein molecules are adsorbed onto the surface of particles of silica gel.
To gather a gas, liquid or dissolved substance on a surface
A method causing a liquid or gas to condense on the surface only of an adsorbing material.
adsorbed; adsorbing. To collect molecules of a substance on a surface.
The act of selectively attracting and holding a gas, vapor, liquid, chemical or colloid onto the surface of a solid. To collect and hold a fluid on the surface of a solid
That which is taken onto the carpet by adherence to the surface (i.e. soot, etc.)
A process by which molecules are taken up on the surface of a solid by chemical or physical action. Large amounts of gases, for example, may be absorbed on the surface of a porous material such as charcoal.
To adhere in an extremely thin layer of molecules (as of gases, solutes, or liquids) to the surfaces of solid bodies or liquids with which a substance is in contact.
To take up and collect molecules of one substance to the surface layer of a solid or liquid with which the molecules come in contact.
