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:

Applicability of gypsum in selective removal of anionic dye molecules from aqueous medium
Mohammad Jobaer Hassan,Md. Fahamidul Islam,Nahida Akter,Md. Nizam Uddin,Abrar Yasir Abir,Sami Ben Aoun,Mohammad A. Hasnat,Mohammad A. Hasnat +7 more
TL;DR: In this article, the authors describe how selectively anionic organic molecules could be removed from aqueous medium using naturally available gypsum (GS) adsorbent, which shows strong interactions with anionic dye molecules while it does not show any affinity towards cationic dye molecules.
Thermodynamic parameters for adsorption equilibrium of methylene blue from aqueous solutions with low-cost adsorbents
TL;DR: In this paper, the authors deal with thermodynamic parameters published for the adsorption of methylene blue (MB) on different low-cost adsorbents and compare the enthalpy change (ΔH°) and entropy change(ΔS°) for two groups of inorganic and natural or lignocellulosic adorbents.

Study of the Removal of Safranine-O Dye from Wastewater Using Waste Derived Biosorbent
Sorption Studies on the Removal of Industrial Dye Aniline Yellow From Aqueous Solution Using Surfactant Modified Iron Filings
TL;DR: Ngwu et al. as mentioned in this paper used SDS-coated iron filings as an anionic surfactant to remove aniline yellow from aqueous solutions and found that the adsorption process was pH-dependent.

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.
