Synthesis and performance evaluation of chitosan/zinc oxide nanocomposite as a highly efficient adsorbent in the removal of reactive red 198 from water

In this study, Chitosan and Chitosan-zinc oxide (ZnO) nanocomposite were prepared applied as a low-cost adsorbent with high adsorption capacity for removing reactive red 198 (RR 198) dye from contaminated water. After preparation, it was characterized using FT-IR, XRD, SEM. The effect of pH, temperature, time, amount, initial concentration investigated in the removal efficiency RR 198. maximum (qm) obtained Langmuir equation 172.41 mg/g dose 0.1 g/L, pH: 4, temperature 25°C, time 40 min. thermodynamic parameters demonstrated spontaneous endothermic nature process. Due to chitosan/ZnO water advantages such capacity, simple synthesis, easy application, can be used an effective method
