Journal ArticleDOI
Dye and its removal from aqueous solution by adsorption: A review
TL;DR: An extensive list of various adsorbents such as natural materials, waste materials from industry, agricultural by-products, and biomass based activated carbon in the removal of various dyes has been compiled here.
Journal ArticleDOI
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
A review on chemical coagulation/flocculation technologies for removal of colour from textile wastewaters.
TL;DR: Some novel pre-hydrolysed coagulants such as Polyaluminium chloride (PACl), Polyal aluminium ferric chloride (PAFCl), Polyferrous sulphate (PFS) and Polyferic chloride (PFCl) have been found to be more effective and suggested for decolourisation of the textile wastewater.
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
Efficiency of various recent wastewater dye removal methods: A review
TL;DR: In this article, a review of existing research papers on various biological, chemical and physical dye removal methods to find its efficiency through percentage of dye removal is presented, which highlights enzyme degradation and adsorption (physical) dye removal as these are known as one of the most efficient dye removal techniques these days.

Journal ArticleDOI
Adsorption of acid dye onto activated carbons prepared from agricultural waste bagasse by ZnCl2 activation.
TL;DR: The Langmuir model appears to fit the isotherm data better than the Freundlich model and the physical properties of these adsorbents were consistent with the parameters obtained from theIsotherm equations.
Journal ArticleDOI
Adsorption of reactive dye from an aqueous solution by chitosan: isotherm, kinetic and thermodynamic analysis.
TL;DR: The results indicate that chitosan is suitable as adsorbent material for adsorption of reactive dye form aqueous solutions, and demonstrates that intraparticle diffusion plays a significant role in the adsorptive mechanism.

Removal of chrome dye from aqueous solutions by mixed adsorbents fly ash and coal
G.S. Gupta,G. Prasad,V. N. Singh +2 more
TL;DR: In this article, the removal of Omega Chrome Red ME (a popular chrome dye) from its aqueous solutions by adsorption on a homogeneous mixture of fly ash and coal in different proportions has been carried out.
Journal ArticleDOI
Activated carbons developed from surplus sewage sludge for the removal of dyes from dilute aqueous solutions
TL;DR: In this paper, sludge-based (SB) activated carbon (AC) was used for removal of three anionic dyes in solution (CI Acid Brown 283, CI Direct Red 89 and CI Direct Black 168).

TL;DR: It was found that the sufficient time to attain equilibrium was 90 min and the Langmuir isotherms was the best-fit adsorption isotherm model for the experimental data obtained from the non-linear chi-square statistic test.
