Aniline Adsorption from Effluent Synthetic by Magnetic Nanoparticles of Iron Oxide (Fe3O4) and Activated Carbon

Document Type : Research Paper



In this study powder activated carbon (PAC) and Fe3O4 magnetic nanoparticles were combined by using co-precipitation method to preparation of magnetic nanoparticles Fe3O4-activated carbon (Fe3O4-AC MNPs) as an adsorbent for removal of aniline from wastewater. Physical characteristic properties of adsorbent were analyzed by SEM, TEM, XRD and BET. Also, the effect of various parameters such as pH, contact time, adsorbent dosage, initial aniline concentration and solution temperature were investigated. The experimental data considered by Langmuir and Freundlich adsorption isotherms and two models kinetically of pseudo first-order and pseudo second-order. The results showed that the adsorption followed Langmuir and pseudo second-order models. According to Langmuir isotherm, the maximum adsorption capacity was 90.91 mg/g at pH 6, and adsorbent (magnetic activated carbon) due to have advantages such as easy and rapid separation from solution could be applied as an effective and useful adsorbent for removal of pollutants from water and wastewater.
