Adsorption kinetics and thermodynamics of an anionic dye onto sepiolite
TL;DR: In this article, the adsorption kinetics of CI reactive blue 221 (RB221) onto sepiolite were investigated in aqueous solution in a batch system with respect to stirring speed, contact time, initial dye concentration, pH, and temperature.

Adsorption of a cationic dye (methylene blue) onto spent activated clay
Chih-Huang Weng,Yi-Fong Pan +1 more
TL;DR: The adsorption characteristics of methylene blue onto spent activated clay, a waste produced from an edible oil manufacturer was investigated and a modified double exponential equation accounting both with chemical and mathematical point of view was proposed to describe the adsorptive kinetic data.

Methylene blue adsorption from aqueous solution by dehydrated peanut hull
TL;DR: Dehydrated peanut hull as an agricultural by-product was used for adsorption of methylene blue from aqueous solution and it was found that at the higher initial MB concentration, intraparticle diffusion is becoming significant controlling step.
Journal ArticleDOI
Cellulosic substrates for removal of pollutants from aqueous systems: a review. 1. metals
TL;DR: In this article, the authors consider how biosorption of dyes onto cellulose-related materials has the potential to address the concerns of highly visible, sometimes toxic, and sometimes resistant to biological breakdown; thus it is important to minimize their release into aqueous environments.

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.
