Sustainable utilization of the bauxite residue (red mud) generated from the alumina refining
has recently increased due to increased environmental concerns because of its high …

Industrial wastes, such as, fly ash, blast furnace slag and sludge, black liquor lignin, red
mud, and waste slurry, etc. are currently being investigated as potential adsorbents for the …

Emerging pollutants in the marine ecosystem, as well as their possible impact on live
species, have become a rising cause of worry. A traditional wastewater treatment plants …

Fly ash and red mud have been employed as adsorbents for the removal of a typical basic
dye, methylene blue, from aqueous solution. Heat treatment and chemical treatment have …

Red mud (RM) is a by-product of bauxite processing via the Bayer process. Its disposal
remains an issue of great importance with significant environmental concerns. In the past …

The present study deals with the competitive adsorption of cadmium (Cd (II)) and nickel (Ni
(II)) ions onto bagasse fly ash (BFA) from single component and binary systems. BFA is a …

The biosorption of cadmium and nickel onto grapefruit peel from aqueous solution has been
investigated using batch technique. Experiments are carried out as a function of solution pH …

A new biosorbent for removing toxic metal ions from water/industrial wastewater has been
investigated using by-product lignin from paper production. Lignin was extracted from black …

Bauxite residue (red mud) is a solid waste produced in the process of alumina extraction
from bauxite. More than 70 million tons of bauxite residue is generated annually. Presently, it …

This paper describes the removal of fluoride from water using granular red mud (GRM)
according to batch and column adsorption techniques. For the batch technique, the …
