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.
Journal ArticleDOI
Dye and its removal from aqueous solution by adsorption: A review
TL;DR: An extensive list of various adsorbents such as natural materials, waste materials from industry, agricultural by-products, and biomass based activated carbon in the removal of various dyes has been compiled here.

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.

Kinetic Studies of Competitive Heavy Metal Adsorption by Sphagnum Moss Peat
TL;DR: In this article, the results of an examination into the adsorption by peat of copper and nickel from both mono and bi-solute systems were presented, and it was shown that pore diffusion appeared to be the rate-controlling step and that the presence of ‘contaminant’ copper ions reduced the binding of nickel.
Journal ArticleDOI
Removal of dyes from aqueous solutions by cellulosic waste orange peel
TL;DR: In this paper, the adsorption of dyes such as congo red, procion orange and rhodamine-B by waste orange peel was examined at different concentrations of dye, adsorbent dosage, agitation time and pH.
Journal ArticleDOI
Copper(II) removal from aqueous solutions by fly ash
TL;DR: In this article, the removal of Cu(II) by adsorption on fly ash has been found to be concentration, pH and temperature dependent, indicating the process to be diffusion controlled.

Batch nickel removal from aqueous solution by sphagnum moss peat
TL;DR: In this article, the batch adsorption of Ni(II) onto sphagnum moss peat has been studied, and the reaction was pH dependent, the optimum range being 4.0-7.0.
