Dye sequestration using agricultural wastes as adsorbents

Elimination of Heavy Metals from Wastewater Using Agricultural Wastes as Adsorbents

The adsorption process is being widely used by various researchers for the removal of heavy metals from waste streams and activated carbon has been frequently used as an adsorbent. Despite its extensive use in the water and wastewater treatment industries, activated carbon remains an expensive material. In recent years, the need for safe and economical methods for the elimination of heavy metal...

Agricultural and agro-processing wastes as low cost adsorbents for metal removal from wastewater: A review

This study reviews the use of agricultural and agro-processing industry wastes as metal adsorbents from wastewater. Modified materials displayed better adsorption capacity and capability of some was comparable with that of commercial activated carbons and synthetic resins. Agricultural wastes are low-cost adsorbents and can be viable alternatives to activated carbon for treatment of metal-conta...

Agricultural wastes as a low cost adsorbents for the removal of Acid Blue 92 dye: A Comparative study with Commercial activated carbon

In the present study, activated carbons of Eichornea crasssipes(EC), Sugarcane bagassae(SB), Tea waste(TW) and Guava leaf(GL) were prepared from agricultural wastes and used as an adsorbents for the removal of Acid Blue 92 (AB92) dye from aqueous solution. The effects of pH, adsorbent dosage, initial dye concentration and contact time on the extent removal of AB92 has been studied by Batch adso...

Use of Cellulosic Materials as Dye Adsorbents — A Prospective Study

Cellulose is the most abundant biopolymer of nature, and it is widely used in the syn‐ thesis of new materials as well as in the adsorption of dye. This study reports a litera‐ ture review (articles) and technology review (patents) about publications and product invention, which contain information on the use of cellulose on the adsorption of dyes in the period 2004–2014. For this work, researc...
