Copper, zinc, cadmium and lead biosorption by Gymnogongrus torulosus. Thermodynamics and kinetics studies
TL;DR: Kinetic experiments demonstrated that fast metal uptakes follow a pseudo-second-order kinetic model and that intra-particle diffusion and/or chemisorption were the rate-limiting steps.

Adsorptive potential of agricultural wastes for removal of dyes from aqueous solutions
TL;DR: In this paper, the authors investigated the adsorptive characteristics of agricultural wastes (Citrus Limetta Peel and Zea Mays Cob) for effective removal of dyes from aqueous solutions.

Mohammad Foroughi-Dahr,Hossein Abolghasemi,Mohammad Esmaili,Alireza Shojamoradi,Hooman Fatoorehchi +4 more
TL;DR: The feasibility of using tea waste (TW) as a low-cost adsorbent for the adsorption of an anionic dye (Congo red) from aqueous solution has been investigated as discussed by the authors.

Magnetic MCM-41 silica particles grafted with poly(glycidylmethacrylate) brush: Modification and application for removal of direct dyes
TL;DR: In this article, magnetic MCM-41-g-p(GMA)-TAEA particles were grafted with tris(2-aminoethyl)amine (TAEA) and used as a cationic adsorbent for the adsorptive removal of Direct Blue 6 (DB-6) and Direct Black-38(DB-38) from aqueous medium.
Journal ArticleDOI
Design of a new integrated chitosan-PAMAM dendrimer biosorbent for heavy metals removing and study of its adsorption kinetics and thermodynamics.
TL;DR: Thermodynamic and kinetic studies showed that Langmuir isotherm model and pseudo second order kinetic model are more compatible for describing equilibrium data of the uptake capacity and kinetic rate of the Pb(2+) uptake, respectively.

Kinetics of Soil Chemical Processes
TL;DR: The application of chemical kinetics to soil systems is discussed in this paper, where the authors present a model of Inorganic and Organic Reactions in Soils, as well as the mechanisms of Rapid Reactions on Soil Constituents using Relaxation Methods.
