Increasing amount of dyes in the ecosystem particularly in wastewater has propelled the
search for more efficient low-cost adsorbents. The effective use of the sorption properties …

Azo dyes represent the largest class of industrial colorants. These are no longer used only
for the coloration of textiles, plastics, paints, inks, and lacquers, but rather serve as key …

The kinetics of sorption from a solution onto an adsorbent has been explored theoretically.
The general analytical solution was obtained for two cases. It has been shown that at high …

Dyes are usually present in trace quantities in the treated effluents of many industries. The
effectiveness of adsorption for dye removal from wastewaters has made it an ideal …

The effluent water of many industries, such as textiles, leather, paper, printing, cosmetics,
etc., contains large amount of hazardous dyes. There is huge number of treatment …

Adsorption of industrially important dyes namely bromophenol blue, alizarine red-S, methyl
blue, methylene blue, eriochrome black-T, malachite green, phenol red and methyl violet …

Batch sorption experiments were carried out to remove methylene blue from its aqueous
solutions using fly ash as an adsorbent. Operating variables studied were initial dye …

Spent brewery grains (SBG), a by-product of the brewing process, were tested as an
adsorbent of acid orange 7 dye (AO7), a monoazo acid dye currently used in paper and …

Textile wastewater presents a challenge to conventional physico‐chemical and biological
treatment methods. Liquid‐phase adsorption has been shown to be highly efficient for the …

The adsorption of dyes in the solutions using activated sludge might be a promising
approach in wastewater treatment units. The adsorption of Basic Red 18 and Basic Blue 9 …
