The phrase "adsorption zones" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in chemistry or materials science, to refer to specific areas where adsorption occurs.
Example: "The study focused on the adsorption zones within the catalyst to determine their efficiency in chemical reactions."
Alternatives: "adsorption areas" or "adsorption sites".
This indicated that the adsorption zone was almost saturated at the time of exhaustion.
The governing influence of primary adsorption zone formation was characterized by different secondary parameters.
This model predicts the adsorption zone length and height equivalent to theoretical plates (HETPs).
The model was also applied to investigate the NOx adsorption performance in the adsorption zone of an internal circulating fluidized bed deNOx reactor.
The polymer adsorbed onto the tube wall, in the flow of dilute solutions of linear random coiling macromolecules, also produces a concentrated fluid layer at the surface of the adsorption zone, as a result of the flow of the solvent micromolecules in the porous network comprising the adsorption zone.
The kinetics of hydrogenation of a α-methylstyrene to cumene is studied in a multiphase recirculating reactor where the adsorption zone (gas-liquid) is separated from the reaction zone (liquid with dissolved hydrogen-catalyst).
It was shown that the system's maximum removal capacity was based on the rate at which regenerated adsorbent could be added into the adsorption zone as long as sufficient charge had been passed through the adsorbent to restore its adsorptive capacity.
A lower flow rate resulted in a longer contact time as well as shallow adsorption zone.
The dye concentration increased with increasing dye loading rate and driving force for the mass transfer decreased in the adsorption zone length, leading to a net effect of appreciable increase in adsorption capacity (Bennani-Karim et al. 2011).
