Adsorption of basic dyes from aqueous solution onto activated carbons
TLDR
In this article, the authors compared the adsorption capacity of different types of activated carbons produced by steam activation in small laboratory scale and large industrial scale processes and found that activated carbon has the highest adsorptive capacity towards MB dye (588 ǫmg/g), followed by F400 (476 milligrams/g) and PAC1 (380 milligram/g).About:

Adsorption of methylene blue on low-cost adsorbents: A review
TL;DR: It is evident from a literature survey of about 185 recently published papers that low-cost adsorbents have demonstrated outstanding removal capabilities for MB, and these include agricultural wastes, industrial solid wastes, biomass, clays minerals and zeolites.
Journal ArticleDOI
Cationic and anionic dye adsorption by agricultural solid wastes: A comprehensive review
TL;DR: In this paper, the use of agricultural solid wastes to remove two classes of dye, cationic and anionic dyes, was discussed and a simple comparison among cationi-and anionic dye adsorption by the same adsorbent was made, thus possibly opening the door for a better understanding of the dye-classified adaption process.

Removal of methylene blue from aqueous solution by graphene oxide.
TL;DR: Graphene oxide is a highly effective absorbent of methylene blue (MB) and can be used to remove MB from aqueous solution and the results indicate that GO can be applied in treating industrial effluent and contaminated natural water.

A general treatment and classification of the solute adsorption isotherm. I. Theoretical
TL;DR: In this article, a theoretical basis is developed for the classification of adsorption isotherms for solutes in dilute solution, which relates their characteristic shapes to parameters of the solvent and any second solute.
