Adsorption, dyes, beads of chitosan.Abstract
Pollution of waterways by effluents containing dyes generates great concern. To date there is no general method for the decontamination of wastewater from the textile industry. The adsorption process has been highlighted in the industrial sector, mainly due to the low cost and efficiency in removal rates. In this study, the adsorption of dyes for industrial chitosan beads showed that the concentration of the colorant Remazol Turquoise G 133% increases the adsorptive capacity of the beads. Kinetic tests with real effluent sample demonstrated that the adsorption capacity of the material was smaller than that observed with the use of synthetic dye, however, after 24 hours there was a significant drop of sample absorbance, showing that the synthesized material is promising.
