The phrase "adsorption of impurities" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in chemistry or materials science, to describe the process by which impurities adhere to the surface of a solid or liquid.
Example: "The adsorption of impurities on the catalyst surface can significantly affect its performance in chemical reactions."
Alternatives: "attachment of contaminants" or "binding of foreign substances".
A novel mechanism was identified of unsteady-state adsorption of impurities at the crystal surface and their gradual replacement by the crystallizing solute towards the equilibrium occupation of the active sites for growth.
Maintaining the electrode potential within the 'double-layer' region of platinum (at 0.5 V vs rhe) for relatively long periods of time (1 30 min) results in the progressive suppression of H adsorption, owing to the adsorption of impurities blocking active Pt sites.
Thus, the efficient physical adsorption of impurities included in the solutions on the bubble surface is expected.
Competition between various processes such as growth, nucleation, aggregation and adsorption of impurities determines the structure of nanoparticles [27].
Unique properties of micro- and nanobubbles (MNBs), such as a high adsorption of impurities on their surface, are difficult to verify because MNBs are too small to observe directly.
However, too low binding specificity is not preferred, because it would cause the non-specific adsorption of impurities co-recovered with viral particles from environmental samples, which must hamper the interaction between EVBP and viral particles.
First, we consider previously discussed models for growth oscillations34,35,36,37,38, according to which there is strong growth depression due to the adsorption of impurity molecules at the interface.
Possible hindering effects of impurities on the crystal growth were shown to take place because of the adsorption of impurity species on the crystal surface.
The obtained results indicate that the main cause of such behavior is adsorption of trace impurities from solution.
The three steps comprised: (i) the non-catalytic transesterification with supercritical methanol at 280 °C; (ii) the distillation of the unreacted methanol, water and volatile products; and (iii) the adsorption of the impurities with adequate adsorbents.
Mass transfer coefficients for external and internal transport were determined using experimentally established time-concentration curves in batch tests for the adsorption of organic impurities from water on activated carbon particles.
