摘要: In this study, cobalt ferrites (C) decorated onto 2D material (porous graphene (PG)) and 1D (carbon nanofibers (CNF)), denoted as PG-C CNF-C nanocomposites, respectively, were synthesized using solvothermal process. The prepared nanocomposites studied magnetic adsorbents for the removal of lead (cationic) chromium(VI) (anionic) metal ions. structural chemical analysis was conducted different characterization techniques including Brunauer–Emmett–Teller (BET) analysis, field emission-scanning electron microscopy (FE-SEM), Fourier-transform infrared spectroscopy (FTIR), high resolution-transmission (HR-TEM), vibrating sample magnetometer (VSM), X-ray diffraction (XRD), and photoelectron (XPS). Batch mode adsorption studies with to examine their maximum potential chromate Performance parameters (time, pH, adsorbent dosage initial ion concentrations) effecting capacity optimized. Different kinetic isotherm models examined elucidate Synthesized exhibited significant ions that can be further at pilot scale from contaminated water.
