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.
Journal ArticleDOI
Application of biosorption for the removal of organic pollutants: a review
TL;DR: In this article, a review examines a wide variety of microorganisms (fungi, yeasts, bacteria, etc.), which are capable of uptake of organic pollutants, discusses various mechanisms involved in biosorption, discusses the effects of various parameters such as pH, temperature, concentrations of organic pollutant, other ions, and biomass in solution, pretreatment method, etc.

Soil interactions of herbicide-derived aniline residues: a thermodynamic approach1
A. Moreale,R. Van Bladel +1 more
TL;DR: In this article, a thermodynamic study of the interaction between soil and aniline residues was conducted and it was shown that diffusion processes of p-chloroaniline within a porous adsorbent, like Soignies soil organic matter, must play a leading part in the overall energetic process of the adsorption reaction.
Journal ArticleDOI
Adsorption of lauryl benzyl sulphonate on algae
TL;DR: In this paper, the residue from the extraction of agar-agar from Gracilaria debilis was evaluated as a biosorbent for the removal of linear alkyl benzene sulphonate from aqueous solution.
