Use of various adsorbents for the removal color of the reactive dye baths for sustainable production

In this thesis, the removal of Reactive Red 141 from textile wastewater by adsorption method was studied. Color removal by adsorption method was discussed in two separate sections that were continuous system had a fixed bed column and batch system. Commercial organoclay compounds with different properties based on montmorillonite were used as adsorbents. Kinetic and isotherm modeling for the understanding and interpretation of organoclay adsorption mechanisms were performed. In addition, the results were statistically modeled to determine the appropriate range of the parameters affecting the adsorption. Characterization studies of organoclays and selected model dye were completed. Organoclays used in adsorption were compared in terms of their color removal capacities andstudies were performed in the fixed bed column system using organoclay with the highest adsorption ability. The results were evaluated after completion of adsorption experiments with batch and continuous systems.
