Özet
In this study, activated carbon fibers were prepared from textile waste by chemical activation with ZnCl 2 (and coded IPZN1, IPZN2, and IPZN3). After preparation they were characterized by analyses using the BET surface area, FT-IR, and XRD methods. The ability of IPZN1, to remove naproxen sodium from effluent solutions by adsorption was studied. Results were analyzed by the Langmuir, Freundlich, Dubinin-Radushkevich (D-R), Temkin, Frumkin, Halsey and Henderson equations using linearized correlation coefficients at 298 K. The value of Q 0 was determined as 294.11 mg.g -1 and the ?G value of -21.46 kJ.mol -1 for adsorption of naproxen sodium. The fixed-bed adsorption system was used for study of the adsorption of naproxen sodium onto IPZN1. Experiments were conducted to study the effect of flow rate of naproxen sodium. Decreasing the flow rate was found to enhance capacity. The breakthrough data obtained for naproxen sodium was adequately described by the Thomas and Yoon-Nelson adsorption models. This study revealed that ACF is suitable for use as an effective adsorbent for the adsorption of naproxen sodium.
