“…Recently, various kinds of synthetic dyestuffs appear in the effluents of industries, such as textiles, printing, plastics, leather and food [1]. Ubiquitous dyestuffs are one of the most notorious contaminants in aquatic environments because of their huge volume of production from industries, slow biodegradation, decoloration and toxicity.…”

“…Waste red mud: Zhang et al (2014b) used the acid activated (Acid treatment neutralize the alkalinity of red mud, which could also be recognized as a method for activating the material) sintering process red mud (ASRM) for the adsorption of MG. The optimum process variables were found to be pH [ 3.2, 180 min of contact time and 0.25 g/250 mL of adsorbent dosage.…”

Adsorption can be efficiently employed for the removal of various toxic dyes from water and wastewater. In this article, the authors reviewed variety of adsorbents used by various researchers for the removal of malachite green (MG) dye from an aqueous environment. The main motto of this review article was to assemble the scattered available information of adsorbents used for the removal of MG to enlighten their wide potential. In addition to this, various optimal experimental conditions (solution pH, equilibrium contact time, amount of adsorbent and temperature) as well as adsorption isotherms, kinetics and thermodynamics data of different adsorbents towards MG were also analyzed and tabulated. Finally, it was concluded that the agricultural solid wastes and biosorbents such as biopolymers and biomass adsorbents have demonstrated outstanding adsorption capabilities for removal of MG dye.

There is an urgent requirement to devise and develop highly-effective materials for the purification of industrial wastewater. Coloured effluents are particularly problematic due to their toxicity in plants, aquatic organisms and animals, dictating that polymeric adsorbents are highly sought for their capture.Chitosan hydrogels are a cost-effective substrate for the adsorption of dye molecules as they are contain a biopolymeric gelator that can form hydrogels with a polymer content as low as 3% by mass. Such materials are also highly suited for use within a biomedical context as carrier vehicles for the encapsulation and delivery of protein macromolecules, due to their hydrophilic nature. We disclose the capability chitosan-based hydrogels to non-covalently adsorb both reactive and disperse dye molecules, and a model anionic protein from aqueous solution. The materials generated offer both a platform for dye removal from industrial wastewater, and for the encapsulation and pH-mediated release of protein macromolecules.
