  • (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.

    ‘the dye is adsorbed on to the fibre’
    • ‘These species may be metal ions, surface defects, or adsorbed molecules or ions with one or more unpaired electrons.’
    • ‘During this time the dissolved protein molecules are spontaneously adsorbed on the quartz surface.’
    • ‘This procedure leaves for measurements only these molecules that are strongly adsorbed to the glass surface.’
    • ‘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.’
    • ‘In nuclear reactors, control rods adsorb atomic particles and control the power of the reactor.’
    • ‘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.’
    • ‘It has also shed light on how the rhodium metal surface adsorbs and removes carbon monoxide and nitrogen oxide gases in car exhaust converters.’
    • ‘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.’
    • ‘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.’
    • ‘Thus, the adsorption and affinity of each protein studied should be quite different when they are adsorbed on a hydrophobic surface.’
    • ‘Very fine particles adsorb toxic gases and liquids onto their surfaces.’
    • ‘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.’
    • ‘A hydrophilic ion which adsorbs effectively to the surface of the bilayer must necessarily shed its water.’
    • ‘Second, the system will not work for materials that are strongly adsorbed by, or react with, the system components.’
    • ‘In typical experiments, these condensates are adsorbed to surfaces.’
    • ‘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.’
    • ‘This is because a certain number of molecules are needed to adsorb at the surface to affect the surface tension.’
    • ‘Each type of material will move down the column at a different rate, depending on the its solubility and its tendency to be adsorbed.’
