摘要：

In this study, the removal of Congo red (CR) from aqueous solution was investigated using magnetic nanoparticles Mn-ferrites (MnFe2O4). The results indicated that the removal percentages of CR could reach up to 99% within 10.0 minutes under pH 4-9. The formation of hydrogen bond was the main adsorption mechanism. Sorption kinetics data was found to follow the pseudo-second-order model. The overall rate process was mainly controlled by external mass transfer. The sorption behavior could be well interpreted by the Langmuir model with the maximum adsorption capacity of 41.99 mg g(-1) at 298 K. Thermodynamic data indicated a spontaneous and endothermic process.
