The phrase "a decrease in adsorption" is correct and usable in written English.
It can be used in scientific or technical contexts when discussing the reduction of the process by which molecules adhere to a surface.
Example: "The experiment showed a decrease in adsorption of the dye on the activated carbon over time."
Alternatives: "a reduction in adsorption" or "a decline in adsorption".
However, manganese dissolution loss during the delithiation of LiMn2O4 causes a decrease in adsorption capacity and poor cycling stability for these ion-sieves.
The pore size instead of getting widened; becomes blocked, resulting in a decrease in adsorption capacity of LPAC.
Also, the protonation of the active sites on the adsorbents reduces the number of negatively charged sites available for cadmium ions to bind; hence a decrease in adsorption.
Maximum sorption capacity of 36.8 mg g−1 for SHP showed a decrease in adsorption capacity, and a significant improvement was observed for SKOH (212.8 mg g−1) over SW (83.5 mg g−1) in Table 1.
As a rule, a specific literature reports that a temperature increase causes a decrease in adsorption within liquid/solid systems, since higher temperature rates increase solubility and consequently a decrease in chemical potential, with less adsorption (Khattri and Singh 2000).
The results indicate that the maximum uptake of Cu II) (3.13 mg/g) was obtained at the pH 6. Increasing the pH from 6.5 to 12, a decrease in adsorption capacity was observed.
As adsorption proceeded, the ratio of MB molecules to available adsorption sites decreased, which resulted in a decrease in the adsorption rate until equilibrium was reached [34].
It is clear that precipitation of Pb2+ in the form of Pb(OH 2 at pH > 7 can be decreased the adsorption of Pb2+ ions, which cause a decrease in the adsorption yield.
In addition, the introduction of oxygen groups produces a decrease in the adsorption capacity.
Many of these studies also showed a decrease in the adsorption of metal ions in the presence of electrolytes.
Increasing the solution pH from 2 to 8, resulted in a decrease in the adsorption of Cr VI) from 23.75 to 9.02 mg/g (Fig. 2).
