One-step facile synthesis of mesoporous graphene/Fe3O4/chitosan nanocomposite and its adsorption capacity for a textile dye
TL;DR: In this article, a hierarchical mesoporous graphene-Fe 3 O 4 @chitosan hybrid was prepared by a one-step facile solvothermal method, and the results showed that the incorporation of Fe 3 o 4 in the nanocomposite was confirmed by FT-IR and XRD.

Omid Moradi,Karim Zare +1 more
TL;DR: In this paper, the adsorption kinetics and thermodynamics of Pb(II), Cd(II) and Cu(II)-I ions in aqueous solutions on single-walled carbon nanotube (SWCNTs) and carboxylate group functionalized singlewalled single-wired carbon nanotide (CNT-COOH) surfaces were by atomic absorption spectroscopy.

Use of banana trunk waste as activated carbon in scavenging methylene blue dye: Kinetic, thermodynamic, and isotherm studies
Mohammed Danish,Tanweer Ahmad,Shahnaz Majeed,Mehraj Ahmad,Lou Ziyang,Zhou Pin,S. M. Shakeel Iqubal +6 more
TL;DR: In this article, the authors used activated carbon (BTAC) derived from the banana trunk to scavenge the methylene blue (MB) dye from synthetic dye solution and reached equilibrium within 20 minutes of contact time.

Effective removal of dyes from aqueous solution using ultrafine silk fibroin powder
TL;DR: In this paper, the authors used ultrafine silk fibroin powder as low-cost adsorbent to remove dyes in the printing and dyeing wastewater, and showed that the silk powder with an average diameter of 3.8μm was dominant in β-sheet structure.

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.
