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.

Adsorption of metal complex dyes from aqueous solutions by pine sawdust
Mahmut Özacar,I. Ayhan Şengil +1 more
TL;DR: The results indicate that pine sawdust could be employed as low-cost alternative to commercial activated carbon in aqueous solution for the removal of metal complex dyes.
Journal ArticleDOI
Kinetics, isotherm and thermodynamic studies of adsorption of Acid Blue 193 from aqueous solutions onto natural sepiolite
TL;DR: In this article, natural sepiolite was used as an adsorbent for the investigation of the adsorption kinetics, isotherms and thermodynamic parameters of an acid dye (Acid Blue 193, AB193) from aqueous solution at various pHs, temperatures and concentrations.
Journal ArticleDOI
Adsorption of malachite green on groundnut shell waste based powdered activated carbon
TL;DR: Results of comparative adsorption capacity of both carbons indicate that groundnut shell can be used as a low-cost alternative to commercial powdered activated carbon in aqueous solution for dye removal.
Journal ArticleDOI
Evaluation of the performance of adsorption and coagulation processes for the maximum removal of reactive dyes
TL;DR: In this paper, the effectiveness of combined processes of adsorption and coagulation for complete removal of dyes was also investigated, where a coconut-based powdered activated carbon (PAC) was used as an adsorbent and alum chloride as a coagulant.
Journal ArticleDOI
Photochemical degradation of the hazardous dye Safranin-T using TiO2 catalyst.
TL;DR: It is found that under the influence of TiO2 as catalyst the colored solution of the dye Safranin-T becomes colorless and the process follows first-order reaction kinetics, which implies that the photodegradation throughTiO2 is a safer technique.
