Adsorptive Treatment of Textile Effluent Using Chemically Modified Chitosan as Adsorbent
Ana Lilia Ramos-Jacques, Miriam Estevez, Angel Ramón Hernandez-Martinez
The textile industry produces large quantities of wastewater containing several chemicals (used for preparing, purifying, coloring and finishing textile products). Different treatments methods must be used in stages to safely discharge textile effluent. One of the main pollutants of these effluent is a textile dye, which can been removed by adsorption. Chitosan has excellent properties as adsorbent and has been chemically modified to enhance its performance. The best results in modifying Chitosan were achieved using nanomaterials as part of composites. Chitosan could not yet be replaced as an adsorbent by other chemical compounds because it is relatively inexpensive and has high adsorption capacity.
