adsorb

verb ədˈsɔːbədˈzɔːb

[with object]Chemistry

(of a solid) hold (molecules of a gas or liquid or solute) as a thin film on the outside surface or on internal surfaces within the material.

Example sentencesExamples
- In the open atmosphere many solid materials are covered by a layer of molecules adsorbed from the gas.
- He experimented by exposing paraffin wax to crushed Salvia leaves and found the solid wax readily adsorbed the volatile terpenes from the air.
- Thus, the adsorption and affinity of each protein studied should be quite different when they are adsorbed on a hydrophobic surface.
- In typical experiments, these condensates are adsorbed to surfaces.
- Very fine particles adsorb toxic gases and liquids onto their surfaces.
- However, the addition of solid phosphate was not used in subsequent experiments in view of the tendency of flavonoids to adsorb onto solid surfaces.
- The solute is generally a charged ion which can be adsorbed to the surface, absorbed into the surface, or undergo ion exchange with ions in the mineral.
- It has also shed light on how the rhodium metal surface adsorbs and removes carbon monoxide and nitrogen oxide gases in car exhaust converters.
- These species may be metal ions, surface defects, or adsorbed molecules or ions with one or more unpaired electrons.
- This is because a certain number of molecules are needed to adsorb at the surface to affect the surface tension.
- This is most likely to be due to variation in Fe distribution within and adsorbed by plant tissues, and it was particularly evident in the root samples.
- A hydrophilic ion which adsorbs effectively to the surface of the bilayer must necessarily shed its water.
- The catalyst adsorbs both the carbon compound and the hydrogen gas on its surface, in such a way that the molecules are arranged in just the right position for addition to occur.
- Each type of material will move down the column at a different rate, depending on the its solubility and its tendency to be adsorbed.
- This procedure leaves for measurements only these molecules that are strongly adsorbed to the glass surface.
- During this time the dissolved protein molecules are spontaneously adsorbed on the quartz surface.
- Second, the system will not work for materials that are strongly adsorbed by, or react with, the system components.
- The pretreatment by transition metal cations helps to adsorb DNA on mica because it neutralizes the mica surface charge and then weakens the repulsive pressure.
- In nuclear reactors, control rods adsorb atomic particles and control the power of the reactor.
- This should not be taken to mean that the steel surface must be awash in water; a very thin adsorbed film of water is all that is required.

adsorbable

adjective

Chemistry

adsorption

noun ədˈsɔːpʃ(ə)nədˈzɔːpʃ(ə)n

mass noun

Chemistry

The process by which a solid holds molecules of a gas or liquid or solute as a thin film.
the study of the direction of protein adsorption to solid surfaces
Example sentencesExamples
- Acidic lipids enhance the adsorption of positive ions due to their negative charge.
- A distinction can also be made between monolayer adsorption and multilayer adsorption.
- In addition, the surface atoms are capable of both adsorption and absorption of chemical compounds.

adsorptive

adjective

The institution is performing general membrane research and has recently started working on ceramic membranes and chitosan-based adsorptive membrane systems.
Example sentencesExamples
- Soils high in organic matter or clay are more adsorptive than coarse sandy soils.
- The first model focuses on surfaces expanding as a result of adsorptive processes.
- The use of adsorptive agents decreases the amount of the toxic agent available for absorption by the gastric mucosa.
