TLDR
In this paper, a review of the research findings attempted in yester years for the removal of such metals from aqueous solutions by using waste materials from industries, such as blast furnace sludge, slag and flue dust, fly ash, black liquor lignin, and red mud.Abstract:
Presence of toxic and recalcitrant heavy metal ions in industrial effluents is a major environmental concern. These fatal metal ions are not only hazardous in exceeding concentrations but due to the property of biomagnification it is urgent to look for the plausible solutions. This review article is an attempt to gather the research findings attempted in yester years for the removal of such metals from aqueous solutions by using waste materials from industries, such as blast furnace sludge, slag and flue dust, fly ash, black liquor lignin, and red mud. Studies have been complied keeping various efficiency influencing parameters such as optimum dose, contact time, initial concentration of metal ions, and many more in consideration. This article also tries to summarize the various problems and shortcoming of the work carried so far and attempts to explore the feasible suggestions.read more

Removal of dyes from aqueous solution using fly ash and red mud.
TL;DR: Fly ash and red mud have been employed as adsorbents for the removal of a typical basic dye, methylene blue, from aqueous solution and it is found that fly ash generally shows higher adsorption capacity than red mud.

Removal of heavy metals from industrial wastewaters by adsorption onto activated carbon prepared from an agricultural solid waste
TL;DR: The percent adsorption increased with increase in pH from 2 to 6 and remained constant up to 10 and the resulting carbon is expected to be an economical product for the removal of toxic heavy metals from industrial wastewaters.
