Abstract
The MnFe2O4/diatomite was obtained by wet chemical methods. The specific structure of the material has been determined by modern physicochemical methods. The results showed that the surface of diatomite was coated by the manganese/iron oxide nanoparticles. The prepared MnFe2O4/diatomite material is a good adsorbent for the removal methylene blue (MB) in water. The adsorption kinetics of MB on modulation materials are consistent with the pseudo-second-order kinetics model. The adsorption isotherms well followed the Langmuir isotherm model and maximal adsorption capacity of MB can read 151.52 mg/g at 323K. The adsorption behavior of MnFe2O4/modified is an endothermic and spontaneous process. The results show that MnFe2O4/diatomite is a promising adsorbent for the efficient removal of cationic dyes from wastewater.
