摘要: Activated carbon (AC)/CoFe2O4 nanocomposites, MAC-1 and MAC-2, were prepared by a simple pyrolytic method using mixture of iron(III)/cobalt(II) benzoates oxalates, respectively, used as efficient adsorbents for the removal amoxicillin (AMX) paracetamol (PCT) aqueous effluents. The synthesized nanocomposites characterized X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), vibrating sample magnetometry (VSM), scanning electron microscopy (SEM), energy dispersive (EDX) transmission (TEM). sizes cobalt ferrite nanoparticles formed from oxalates precursors in ranges 5–80 6–27 nm, respectively. saturation magnetization (M s), remanence r) coercivity (H c) MAC-2 found to be 3.07 emu g−1, 1.36 emu g−1 762.49 Oe; MAC-1, they 0.2989 emu g−1, 0.0466 emu g−1 456.82 Oe. adsorption kinetics isotherm studies investigated, results showed that as-prepared could utilized an efficient, magnetically separable adsorbent environmental cleanup. maximum sorption capacities obtained 280.9 444.2 mg g−1 AMX 215.1 399.9 mg g−1 PCT Both successfully simulated hospital effluents, removing at least 93.00 96.77% nine pharmaceuticals with high concentrations sugars, organic components saline concentrations.
