The phrase "a decrease in sorption" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in discussions related to chemistry, environmental science, or material science, where sorption refers to the process of absorption or adsorption.
Example: "The study revealed a significant decrease in sorption of the contaminant in the treated soil samples."
Alternatives: "a reduction in sorption" or "a decline in sorption".
While the presence of citrate had no effect on Cd II) sorption at pH < 4, it led to a decrease in Cd sorption under slightly acidic to alkaline pH range depending on the concentration of citrate used.
After equilibrium was achieved, there was a decrease in oil sorption capacity with increase in the initial crude oil concentration.
As time precedes this concentration is reduced due to the accumulation of phenol particles in the vacant sites leading to a decrease in the sorption rate at the larger stages from 30 to 1,440 min.
Sahai et al [26] concluded that the absence of a strontium carbonate precipitate at pH above 8.7 was due to insufficient carbonate on the surface to nucleate the precipitate, based on a decrease in carbonate sorption on the goethite surface from pH 6 to 10 (using constants from VanGeen et al. [39]).
The interaction of hydrogen ions with an oxygen radical of the CuO NPs/Ag-clinoptilolite zeolite composite body generates hydroxyl groups and lowers the charge of the matrix, which is accompanied by a decrease in the sorption ability of CuO NPs/Ag-clinoptilolite zeolite composite in relation to 90Sr.
A decrease in the sorption capacity at higher speed of agitation may be attributed to improper contact between the dye ions and the binding sites on the biomass, as the suspension is no longer homogenous due to vortex formation, which makes the adsorption of dye ions difficult [38, 39].
A decrease in solution pH resulted in an increase in sorption of the cationic forms of antibiotics suggesting that electrostatic forces are the favored sorption mechanism of sulfamethazine and tylosin.
Sulfamethazine showed a slight decrease in sorption when ionic strength was increased from 50 mM to 250 mM (Table 4).
There is a noticeable decrease in sorption because chromium begins to precipitate as it comes into contact with adsorbent at a pH higher than 4.5 due to the alkaline nature of the adsorbent surface.
