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
Adsorption of basic dye on high-surface-area activated carbon prepared from coconut husk: equilibrium, kinetic and thermodynamic studies.
TL;DR: Coconut husk-based activated carbon was shown to be a promising adsorbent for removal of methylene blue from aqueous solutions and was found to follow closely the pseudo-second-order kinetic model.
Journal ArticleDOI
Hydrothermal conversion of biomass waste to activated carbon with high porosity: a review.
TL;DR: A systematic and critical review of the production of activated carbon from hydrochars is presented in this paper, where the current knowledge gaps and challenges involved in the hydrothermal carbonization of biomass waste are critically evaluated with suggestions for further research.

Removal of anionic dye Congo red from aqueous solution by raw pine and acid-treated pine cone powder as adsorbent: Equilibrium, thermodynamic, kinetics, mechanism and process design
Sara Dawood,Tushar Kanti Sen +1 more
TL;DR: In this article, a single-stage batch absorber design for the Congo red adsorption onto pine cone biomass was presented based on the Freundlich isotherm model equation.
Journal ArticleDOI
Agricultural based activated carbons for the removal of dyes from aqueous solutions: a review.
TL;DR: This review evaluates a number of different agricultural waste adsorbents and types of dyes to determine whether low cost adsorbent derived from agricultural wastes can be viable alternatives to activated carbon for the treatment of contaminated wastewater.

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.
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.
Journal ArticleDOI
Kinetics and mechanism of removal of methylene blue by adsorption on various carbons—a comparative study
TL;DR: In this article, the kinetics and mechanism of methylene blue adsorption on commercial activated carbon and indigenously prepared activated carbons from bamboo dust, coconut shell, groundnut shell, rice husk, and straw, have been studied.
Journal ArticleDOI
Adsorption of methylene blue on kaolinite
TL;DR: In this paper, methylene blue was adsorbed on kaolin from a local deposit and the adsorption data could be fitted by the Freundlich and Langmuir equations.
