Kinetics and thermodynamics of Methylene Blue adsorption on Neem (Azadirachta indica) leaf powder
TLDR
In this article, Methylene blue was adsorbed on an adsorbent prepared from mature leaves of the Neem tree (Azadirachta indica), and a batch adsorption study was carried out with variable adsorbate concentration, adsorbant amount, pH, and temperature.About:

Removal of hazardous dye from synthetic textile dyeing and printing effluents by Archis hypogaea L. shell: a low cost agro waste material
G.H. Sonawane,V.S. Shrivastava +1 more
TL;DR: In this article, a batch isotherm model based on the assumption of a pseudo second order mechanism has been used to predict the rate constant of sorption and the equilibrium capacity with the effect of mass of adsorbent, initial dye concentration, pH and contact time.

Kinetics of Adsorption on Carbon from Solution
Walter J. Weber,J. C. Morris +1 more
TL;DR: In this paper, it was shown that the rate of adsorption of persistent organic compounds on granular carbon is quite low and the rate is partially a function of the pore size distribution of the adsorbent, of the molecular size and configuration of the solute, and of the relative electrokinetic properties of adsorbate and adsorbents.

Sorption of dye from aqueous solution by peat
Yuh-Shan Ho,Gordon McKay +1 more
TL;DR: In this paper, the sorption of two dyes, namely Basic Blue 69 and Acid Blue 25 onto peat has been studied in terms of pseudo-second order and first order mechanisms for chemical sorption as well as an intraparticle diffusion mechanism process.

Use of cellulose-based wastes for adsorption of dyes from aqueous solutions.
TL;DR: Based on the adsorption capacity, it was shown that banana peel was more effective than orange peel and intraparticle diffusion of dyes within the particle was identified to be rate limiting.
