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.

Photocatalytic oxidation of organic dyes by nano-sized metal molybdate incorporated titanium dioxide (MxMoxTi1- xO6) (M = Ni, Cu, Zn) photocatalysts
Tanmay K. Ghorai,Tanmay K. Ghorai,Debasis Dhak,Debasis Dhak,Soumya Kanti Biswas,Sudipta Dalai,Panchanan Pramanik +6 more
TL;DR: In this paper, different metal molybdates incorporated titanium dioxide were prepared by the chemical solution decomposition (CSD) method, and the prepared nano powders were characterized by XRD, UV-vis spectra, specific surface area (BET), UV diffuse reflectance spectrum, EPR spectrum and TEM analyses.
Journal ArticleDOI
Adsorption of acid dyes from aqueous solutions onto sepiolite
TL;DR: In this article, the adsorption of two acid dyes, namely acid red 57 (AR57) and acid blue 294 (AB294), onto sepiolite was investigated.
Journal Article
A comparative assessment of adsorbents prepared from industrial wastes for the removal of cationic dye
TL;DR: A comparative assessment of adsorbents prepared from industrial wastes for the removal of cationic dye using Na6(CO3SO4)(SO4)2, Na2SO3, and Na2CO3 for adsorbent removal and their applications in selective separation and recycling.
Journal ArticleDOI
Natural waste materials containing chitin as adsorbents for textile dyestuffs: Batch and continuous studies
TL;DR: In this work three natural waste materials containing chitin were used as adsorbents for textile dyestuffs, namely the Anodonta shell, the Sepia and the Squid pens, and Kinetic studies suggested the existence of a high internal resistance in both systems.
Journal ArticleDOI
Decolourisation of cotton bleaching effluent with wood rotting fungus
TL;DR: After the fungal treatment, an improvement in the treatability of the effluent by other microorganisms was observed and the activity of manganese peroxidase (MnP) appeared to correlate well with the decolourisation rate.
