TLDR
Pilot-plant experimental studies have been performed using packed-bed column with different feed concentrations, flow rates and bed heights, to evaluate sorption of Bismark Brown on steam-activated carbon, and the Bed depth service time (BDST) design model have been used to analyze the data.About:

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
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.

A review on utilization of wood biomass as a sustainable precursor for activated carbon production and application
Mohammed Danish,Tanweer Ahmad +1 more
TL;DR: In this article, a detailed list of production methods of activated carbon from wood biomass is presented systematically, and an attempt has also been made to review the physical properties, such as ultimate and proximate analyses of wood biomass material.
Journal ArticleDOI
Dye removal by low cost adsorbents: hazelnut shells in comparison with wood sawdust.
TL;DR: Batch adsorption of Methylene Blue and Acid Blue 25 onto ground hazelnut shells was studied in comparison with sawdust to explore the potential use of this material as low cost adsorbent for dye removal in dyehouse effluents.
Journal ArticleDOI
Dye sequestration using agricultural wastes as adsorbents
TL;DR: A literature survey of about 283 recently published papers shows that low-cost adsorbents have demonstrated outstanding removal capabilities for dye removal and the optimal equilibrium time of various dyes with different charcoal adsorbent from agricultural residues is between 4 and 5h as mentioned in this paper.

Use of activated carbons prepared from sawdust and rice-husk for adsorption of acid dyes: a case study of Acid Yellow 36
TL;DR: In this paper, an acid dye, acid yellow 36, was used as the adsorbate for the removal of acid dyes from aqueous solution and the results showed that a pH value of 3 is favorable for the adsorption of acid dye.
Journal ArticleDOI
Dye removal from aqueous solution by adsorption on treated sawdust.
TL;DR: It is proposed that in batch or stirred tank reactors, both adsorbents can be an attractive option for dye adsorption.

Basic dye (methylene blue) removal from simulated wastewater by adsorption using Indian Rosewood sawdust: a timber industry waste
TL;DR: In this article, the potential use of Indian Rosewood ( Dalbergia sissoo ) sawdust, pretreated with formaldehyde and sulphuric acid, for the removal of methylene blue dye from simulated wastewater was investigated.
Journal ArticleDOI
Utilization of various agricultural wastes for activated carbon preparation and application for the removal of dyes and metal ions from aqueous solutions.
TL;DR: Experimental results show all carbons were effective for the removal of pollutants from water and are expected to be economically viable for wastewater treatment.
