Abstract :
In this research, the adsorption of copper (II) metal ions on activated carbon was investigated using waste PET bottles. Initially, activated carbon was prepared using PET waste bottles and the activated carbon was characterized using XRD, FTIR, BET and SEM analyzes. Then, the adsorption of copper (II) metal ions on the synthesized activated carbon was performed in batch mode. The effects of variables such as initial concentration of copper, temperature, pH and time were investigated and the results showed that the optimum amount of copper ion adsorption was in 50 ppm solution with a pH of 5 and a contact time of 90 minutes and an adsorbent amount of 0.1 g. Isotherms were studied using Langmuir, Freundlich and Temkin models and the adsorption kinetics was investigated using pseudo-first as well as pseudo-second order models. It was observed that the behavior of the desired process follows the Freundlich isotherm and its kinetics corresponds to the pseudo-second order reaction.
