| Özet |
| To increase the adsorption capacity of chitosan (Cht), which is an abundant biopolymer, zirconium (IV)-chitosan (Zr(IV)-Cht) composite was synthesized and adsorption capacity was compared with Cht using acid orange II (T-II). Batch studies were conducted to analyze the effect of Zr (IV) loading amount, solution pH, adsorbent dosage, contact time and temperature on T-II adsorption. The best responding isotherm model to the experimental data was found Langmuir adsorption isotherm model by analyzing Langmuir, Freundlich and Temkin isotherm models. The maximum adsorption capacities were found as 256.41 mg/g and 666.67 mg/g for Cht and Zr(IV)-Cht, respectively. Application of kinetic data to the pseudo-first order and pseudo-second order kinetic models, pseudo-second order model was the best-fitted model for the kinetic data. The adsorption process was found endothermic and spontaneously occurred for both Cht and Zr(IV)-Cht. According to adsorption/desorption experiments, after seventh cycle adsorption capacities were found 65% for Cht and 95% for Zr(IV)-Cht. The synthesized Zr(IV)-Cht composite was found as the high adsorption capacity, low-cost and non-toxic material for T-II adsorption and can be used for dye adsorption. |
