The phrase "adsorption cannot be" is correct and usable in written English.
It can be used in scientific or technical contexts when discussing the limitations or impossibilities related to adsorption processes.
Example: "In certain conditions, adsorption cannot be effectively achieved due to the presence of competing molecules."
Alternatives: "adsorption is not possible" or "adsorption cannot occur".
This result indicated that adsorption cannot be the only mechanism for As III) uptake by Fe-sulfide coating layer.
However, sometimes it is very difficult to get a simple analytical form of adsorption heat equation i.e. the isosteric heat of adsorption cannot be easily calculated from the thermodynamic van't Hoff relation.
Hence, the adsorption cannot be said to be of first order.
Even worse, this undesired adsorption cannot be avoided, since air atmosphere is the natural working condition for gas sensors.
When Ag-EN dissolution is surface area limited, the Ag+ depleted in the media either through particulation or adsorption cannot be replenished right away and [Ag+]T thus decreased with time.
A potential effect of grain size on surface area and therefore As adsorption cannot be ruled out, but it is worth noting that the concentrations of P-mobilizable As vary across 3 orders of magnitude in the three study areas whereas the surface area of median-sized aquifer particles varies by only a factor of 9.
The usefulness of the fractal approach to area calculation in the Pt Ru alloy, where the hydrogen adsorption technique cannot be used, is demonstrated using the kinetics of methanol oxidation.
However, their contributions to the adsorption rate cannot be deduced from this model.
Conventional separation technologies such as adsorption and extraction cannot be applied effectively due to the difficulties in regeneration of adsorbents and entrainment of the solvent.
So, the CO2 adsorption results for the CDCs cannot be explained by classical adsorption theories.
This indicated that the adsorption is not reversible and complete regeneration cannot be obtained by adsorption of the material after adsorption.
