Adsorption Rate of 198 Reactive Red Dye from Aqueous Solutions by using Activated Red Mud
Backgroud and purpose: Dye is one of the problems of industrial effluent such as textile industries. The dyes can be removed by various methods. Therefore, the aim of this study was the evaluation of adsorption rate of reactive red 198 from aqueous solution by activated red mud. Materials and methods: This research was a lab study. Activated red mud was used as an adsorbent to remove reactive r...
متن کاملEffect of Strong Acids on Red Mud Structural and Adsorption Properties
12 13 The removal of fluoride using red mud has been improved by acidifying red mud with 14 hydrochloric, nitric and sulphuric acid. This investigation shows that the removal of fluoride 15 using red mud is significantly improved if red mud is initially acidified. The acidification of 16 red mud causes sodalite and cancrinite phases to dissociate, confirmed by the release of 17 sodium and alumi...
متن کاملCr(VI) Adsorption on Red Mud Modified by Lanthanum: Performance, Kinetics and Mechanisms
Water pollution caused by the highly toxic metal hexavalent chromium (Cr(VI)) creates significant human health and ecological risks. In this study, a novel adsorbent was used to treat Cr(VI)-containing wastewater; the adsorbent was prepared using red mud (RM) generated from the alumina production industry and the rare earth element lanthanum. This study explored adsorption performance, kinetics...

متن کاملComparison study of phosphorus adsorption on different waste solids: Fly ash, red mud and ferric-alum water treatment residues.
The adsorption of phosphorus (P) onto three industrial solid wastes (fly ash, red mud and ferric-alum water treatment residual (FAR)) and their modified materials was studied systematically via batch experiments. Compared with two natural adsorbents (zeolite and diatomite), three solid wastes possessed a higher adsorption capacity for P because of the higher Fe, Al and Ca contents. After modifi...
