A sol-gel method using citric acid has been used to fabricate nano-sized manganese ferrites (MnFe2O4) under different calcination temperatures. The microstructure and surface morphology of manganese ferrite powders were characterized by BET, FTIR, XRD, SEM-EDX, and TEM. The nano-sized manganese ferrite was examined for adsorption of congo red (CR). As the results, the BET showed the decreasing surface area of manganese ferrites to 4.47 m2/g for calcination temperatures of 800 °C. The XRD pattern also indicated the alteration of amorphous phase to the crystalline structure as the calcination temperature increased. In addition, the EDX analysis of manganese ferrite at 600 °C showed the element distribution of manganese, iron, and oxygen. Beside that, the TEM images of nano-sized manganese ferrites showed a concentrated atomic mass in the exposed region in the bulk structure. Finally, the adsorption experiment showed that the adsorption of CR followed the pseudo-second order, and adsorption equilibrium was best described by the Langmuir model. Therefore, this nano-sized manganese ferrite can be a promising adsorbent for dye and textile industry.Received: 12nd April 2018; Revised: 4h July 2018; Accepted: 13rd July 2018
