In this work, magnetic nanoparticles of MFe2O4 (M: Fe, Mn, Cu and Co) were prepared on the surface of granular activated carbon throughout the impregnation process, employing HNO3 acid as the carbon modifying agent. These adsorbents were employed to assess the adsorption capability of p-chlorophenol from aqueous solution. The adsorbents were characterized by XRD, SEM, EDX and nitrogen adsorption isotherms. Additionally, the impact of various parameters such as pH, contact time was investigated. The results demonstrate that the current phase is mainly- Fe2O3 (maghemite), spinel manganese, copper and cobalt ferrite, respectively. The equilibrium details were best ascribed by the Langmuir model accompanied by high adsorption capacity of 110mg/g for - Fe2O3/ activated carbon. The kinetic experimental analysis of the adsorption model perfectly was correlated to the pseudo – second order kinetics. With the advantages inexpensive and fast processing, these adsorbents could attain promoting application in wastewater treating.
