Abstract :

Abstract: In this research, Initially, activated carbon was prepared using PET waste bottles and the activated carbon was detected using FTIR, BET and SEM analyzes. In the next step, the adsorption of Iron (II) metal ions on the synthesized activated carbon was performed discontinuously.The effects of variables such as initial concentration of Iron, temperature, pH and time were investigated and the results showed that the optimum amount of Iron ion adsorption in 100 ppm solution with a pH of 5 and a contact time of 60 minutes and an adsorbent amount of 0.2 g occurs. Isotherms were studied using Langmuir, Freundlich and Tamkin models and adsorption kinetics using first and second order pseudo-second order models. It was observed that the behavior of the desired process follows the Langmuir, isotherm and its kinetics corresponds to the pseudo- first order reaction.
