Desorption Kinetics at the Solid/Solution Interface: A Theoretical Description by Statistical Rate Theory for Close-to-Equilibrium Systems

TL;DR: In this article , the importance of desorption and regeneration equates that of the adsorption stage, and presents various regeneration methods as well as the influencing parameters, advantages, and disadvantages thereof.

TL;DR: A review of isotherms and kinetics models used for describing adsorption phenomena at the gas-or liquid-solid interface can be found in this article, where the main body of this chapter is divided into two parts: the first part deals with theories and models (isotherms) which are used for representing adsorbing equilibria.

TL;DR: In this article, the authors provide physical insights into the relationship between the Langmuir kinetics with the pseudo first-and second-order (PFO) kinetic models in terms of operating conditions and isotherm parameters.

TL;DR: In this paper, an amino-functionalized hybrid clay composite adsorbents were developed from a combination of biomass-Carica papaya seeds (PS) and Musa paradisiaca (Plantain peels-PP), ZnCl2 and Kaolinite clay to produce new hybrid clay materials with good affinity for phosphate ions.

TL;DR: The theoretical results (derived equations) show that the observed rate constants of pseudo-first-order and pseudo-second-order models are combinations of adsorption and desorption rate constants and also initial concentration of solute.

TL;DR: In this article, the Na-exchanged clinoptilolite in presence of ammonium ions has been analyzed and the selectivity of the Na exchange is calculated by plotting the exchange isotherms relative to the various cations.

TL;DR: A review of the mechanisms of solute sorption onto various biosorbents has been performed in this article, where the mechanisms have been subdivided into reaction based systems and diffusion based systems, and the literature has been reviewed in accordance with these two groups.
