Removal of Synthetic Textile Dyes From Wastewaters: A Critical Review on Present Treatment Technologies
Kamaljit Singh,Sucharita Arora +1 more
TL;DR: In this article, a comparison of the present decolorization/degradation techniques for water-sensitized azo dyes is presented, where the hierarchy of reduce, reuse, and degrade is adopted and measures are taken to remove color from the industrial discharge.

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.

The role of sawdust in the removal of unwanted materials from water.
TL;DR: Sawdust, a relatively abundant and inexpensive material is currently being investigated as an adsorbent to remove contaminants from water as discussed by the authors, and chemical substances including dyes, oil, toxic salts and heavy metals can be removed very effectively with the organic material.

Adsorption behavior of reactive dye in aqueous solution on chemical cross-linked chitosan beads.
M.S Chiou,H.Y Li +1 more
TL;DR: The adsorption mechanism is shown to be the electrostatic interactions between the dye and chitosan beads and the dynamical data fit well with the second-order kinetic model, except for the dry beads fitting better with the first-order model.
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.
