Özet
In this study, adsorption studies of an aqueous solution of malachite green dye were made in a fixed bed using a thermal power plant. The effects of concentration, flow rate, adsorbent amount, and pH on adsorption applications were investigated. Thomas, Adams-Bohart and Yoon-Nelson models were used to evaluate the results obtained. In addition, the correlation between the model and the experimental data was compared using seven non-linear functions, while the adsorption dynamics of the fixed bed column were modeled. Scanning electron microscopy, X-ray diffraction, Fourier-transform infrared spectroscopy were used for the characterization of adsorbents. The results were compared with the results of previous studies and suggestions for adsorption applications were made accordingly. Yoon-Nelson models showed a good agreement with the experimental data. After the calculations, the maximum adsorption capacity of the fly ash dye was determined as 41.453 mg g(-1).
