Sorptionskinetik
Sorptionskinetik, or sorption kinetics, describes the rate at which a solute is transferred from a liquid phase to a solid sorbent (or between phases) and the mechanism by which sorption proceeds. Sorption encompasses adsorption, where molecules adhere to a surface, and absorption, where molecules are taken into the bulk. Kinetic behavior reflects the nature of the interactions, which can be physical (physisorption) or chemical (chemisorption), and is often influenced by diffusion processes both at the external surface and within the sorbent pores.
Several kinetic models are used to interpret sorption data. The pseudo-first-order model describes the rate of
In practice, sorption kinetics inform the design of treatment systems and help compare sorbents in batch and
