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:

Adsorptive removal of crystal violet dye by Azadirachta indica (neem) sawdust: A low-cost bio-sorbent
TL;DR: Azadirachta indica sawdust has been used as a cost-effective natural adsorbent for adsorptive elimination of a cationic dye crystal violet from aqueous emulsion as discussed by the authors .
A versatile amphiprotic cotton fiber for the removal of dyes and metal ions
TL;DR: In this paper, an amphiprotic adsorbent based on cotton fibers was chemically modified with a cationic monomer and anionic monomer (2-acrylamide-2- methyl propane sulfonic acid) respectively, and the results demonstrate that the adsorp- tion equilibrium was reached within 4 h for Congo red (CR) and methylene blue (MB), 2 h for Cu 2? and 3 h for Pb 2?, respectively.

Magnetic nanocomposites prepared from red mud and durian husk as an effective bio-adsorbent for methylene blue adsorption
TL;DR: In this article , a low-cost magnetic biocomposite of magnetic Fe3O4 nanoparticles (NPs) incorporated with biopolymers extracted from durian husk was used for removal of methylene blue (MB) dye.

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.
