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.
Journal ArticleDOI
Utilization of agro-industrial and municipal waste materials as potential adsorbents for water treatment—A review
TL;DR: In this article, an extensive list of low-cost adsorbents (prepared by utilizing different types of waste materials) from vast literature has been compiled and their adsorption capacities for various aquatic pollutants as available in the literature are presented.

The adsorption of gases on plane surfaces of glass, mica and platinum.
TL;DR: In this article, the absorption index at the wave length of the band maximum was found to be proportional to the total concentration of metal at shorter wave lengths, however, deviations were observed, the absorption increasing more rapidly with concentration than Beers' law would demand.

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.
Journal ArticleDOI
Pore and solid diffusion models for fixed-bed adsorbers
TL;DR: In this article, the prosity factor of the pore model is shown to be very important, especially as the porosity decreases, and the importance of the two diffusional models with respect to the predicted breakthrough curves is demonstrated.
