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:

Nigella sativa seed based nanocomposite-MnO2/BC: An antibacterial material for photocatalytic degradation, and adsorptive removal of Methylene blue from water
TL;DR: The results obtained for this study are much better than the previous Methylene blue adsorption studies with acid washed Black cumin seeds and MnFe2O4/BC for which the capacities were 73.529 mg g−1 and 10.070 mg g‐1 at 27 °C, respectively.

Acrylic acid grafted cellulosic Luffa cylindrical fiber for the removal of dye and metal ions.
TL;DR: The formation of new bands in FTIR spectra of grafted sample confirmed the grafting of acrylic acid onto the cellulosic fiber and confirmed the applicability of Langmuir isotherm that assumed a monolayer coverage and uniform activity distribution on the adsorbent surface.

Adsorption of ammonium ion by coconut shell-activated carbon from aqueous solution: kinetic, isotherm, and thermodynamic studies
TL;DR: Coconut shell-activated carbon (CSAC) was prepared and used for the removal of ammonium ion by adsorption techniques and was found to be the most feasible and environmentally friendly with the use of natural-activated adsorbents.

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.
