Kinetic and equilibrium studies: Adsorption of food dyes Acid Yellow 6, Acid Yellow 23, and Acid Red 18 on activated carbon from flamboyant pods

Comparison of Spirulina platensis microalgae and commercial activated carbon as adsorbents for the removal of Reactive Red 120 dye from aqueous effluents

“…Adsorption is one of the most commonly employed methods for the removal of synthetic dyes from aqueous effluents [13,14], due its simplicity and high efficiency, as well as the availability of a wide range of adsorbents that can be applied [11][12][13][14][15][16]. This process transfers the dyes from the aqueous effluent to a solid phase, remarkably decreasing dye bioavailability to live organisms [11,12].…”

Removal of dyes from aqueous solution by activated carbon from sewage sludge of the municipal wastewater treatment plant

“…At present, there is growing interest in using low cost and commercially available materials for the adsorption of dyes. A wide variety of materials, such as fly ash, peat, wood, palm-fruit bunch particles, activated carbon from fertilizer waste, and activated slag, are being used [8][9][10][11].…”

Effect of hard and soft structure of different biomasses on the porosity development of activated carbon prepared under N2/microwave radiations

“…Activated carbons are, therefore, highly invaluable materials as efficient adsorbents for removal of a variety of pollutants, such as dyes [14], heavy metals [15] and pesticides [16]. Synthetic dyes are generally resistant to biodegradation, and physicochemical techniques for their removal, such as adsorption, chemical oxidation, electrocoagulation, and advance oxidation processes have been recently used extensively to comply with more and more stringent legislation regarding maximum allowable dye concentration in discharged wastewater [17,18].…”
