Abstract :The aim of this study is to investigate the utility of chitosan/zeolite composite beads as adsorbent for removal of anionic textile dye, Acid Yellow 204. It was investigated the influence of parameters such as pH, time, zeolite content in the composite structure, electrolyte concentration, dye concentration and sorbent dosage on the efficiency of dye removal. It was determined that the adsorption capacity increased significantly with decreasing pH Langmuir and Freundlich isotherm models were applied to the experimental data to determine the adsorption mechanism. and The Langmuir isotherm model was determined to be more consistent with the experimental data. It was observed that the reaction kinetics is suitable for the pseudo-second-order.
Keywords : Zeolite, chitosan, acidic dye, adsorption
