The word "adsorption" is correct and usable in written English.
It is a process by which atoms, ions, or molecules are taken up and held on the surface of a solid or liquid. For example, in a water filtration system, the filter material adsorbs (takes up) the dirt and particles in the water, keeping the water clean.
But adsorption should affect other gases, too.
One of the liquids is held stationary by strong adsorption on the surface of a finely divided solid while the other flows through the interstices of the solid particles.
R. arrhizus (R. oryzae) is useful for the production of lactic acid and cortisone, for alcoholic fermentation, and for the biosorption (passive adsorption of chemical contaminants by an organism) of heavy metals.
Chemisorption can occur over a wide temperature range, the most effective temperature for adsorption depending on the nature of the catalyst.
This conclusion is confirmed by measurement of rate of adsorption of nitrogen on the iron catalysts.
Another kind of indicator is the adsorption indicator, the best-known representative of which is the dye fluorescein.
This may include secondary treatment followed by granular media filtration, ultraviolet radiation, granular activated carbon adsorption, reverse osmosis, air stripping, ozonation, and chlorination.
An effective method for removing dissolved organic substances that cause tastes, odours, or colours is adsorption by activated carbon.
Unlike conventional adsorbants, such as activated carbons and zeolites, the new compound showed a selective adsorption of acetylene (C2H2) compared with carbon dioxide (CO2), its molecular cousin.
In about a dozen repetitions of the experiment, the team of scientists produced 17 atoms of mendelevium, which were identified by the ion-exchange adsorption-elution method (mendelevium behaved like its rare-earth homologue thulium) and by the electron-capture decay of its daughter isotope fermium-256.
It follows from such considerations that whereas physical adsorptions, which parallel the ease of liquefaction of the adsorbed substance, occur spontaneously, chemisorption, which involves the making and breaking of chemical bonds, often requires activation energies (energy needed to initiate reactions) as do uncatalyzed chemical processes.
