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.

Kinetics of trace metal sorption to estuarine suspended particulate matter
TL;DR: In this paper, a three-step first order reversible kinetic model is used to fit mesured data for sorption and desorption over periods of up to 200h, which is likely to perform better than the equilibrium partitioning approach under rapidly changing environmental conditions which exist in estuaries.

Efficient Removal of Cadmium Ions from Aqueous Solutions by Hydrous Ceric Oxide - A Radiotracer Study
TL;DR: In this paper, the adsorption of cadmium ions on hydrous ceric oxide has been studied as a function of concentration (10~10~ M), temperature (303-333 K), and pH (7.08-10.47).
