Review of second-order models for adsorption systems.
TL;DR: An overview of second-order kinetic expressions is described in this paper based on the solid adsorption capacity, which shows that a pseudo-second-order rate expression has been widely applied to the Adsorption of pollutants from aqueous solutions onto adsorbents.

Biosorbents for heavy metals removal and their future
Jianlong Wang,Can Chen +1 more
TL;DR: The biosorbents widely used for heavy metal removal were reviewed, mainly focusing on their cellular structure, biosorption performance, their pretreatment, modification, regeneration/reuse, modeling of biosor adaptation (isotherm and kinetic models), the development of novel biosorbent, their evaluation, potential application and future.
Journal ArticleDOI
Kinetic models of sorption: a theoretical analysis.
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.

Kinetics of Mercury(II) Adsorption and Desorption on Soil
TL;DR: In this paper, the authors investigated the mechanism controlling the retention and release reaction rates of Hg(II) on soil using a stirred-flow method and determined the apparent adsorption and desorption rate coefficients by a one-site second-order kinetic model.
