Preparation of eco-friendly and reusable nanocomposites using activated carbon and tartaric acid and their application in removing heavy metal ions from contaminated waters

In the present study, activated carbon was prepared from pistachio shells. Modification of activated carbon levels was performed to increase adsorption capacity using iron nanoparticles and tartaric acid derivatives. The thermal analysis (TG), X-ray diffraction (XRD), TEM and vibrating sample magnetometer (VSM) were used to identify of the nanocomposites. Batch experiments were used to evaluate the ability of nanocomposites to remove heavy metal ions such as lead, cadmium, chromium from contaminated waters. The Langmuir and Freundlich adsorption isotherms were utilized to evaluate the adsorption performance. High adsorption capacity, low cast, recyclability and easyseparation are the advantages of this adsorbent.
