Simple and green synthesis of mesoporous ZnFe2O4 by SDS surfactant and its application as adsorbent of methylene blue from aqua media

In this study, mesoporous ZnFe2O4 was synthesized via a simple and green hydrothermal method in presence of SDS as surfactant and analyzed by XRD, FT-IR, SEM, VSM, DRS and BET techniques. The SEM images showed that prepared particles had sizes about 50-150 nm. The obtained result from BET analysis show that mean of diameter of hollows were about 8.45 nm. The area and volume of hollows were 161.87 m2/g and 0.34 cm3/g, respectively. The VSM curve of mesoporous ZnFe2O4 showed the magnetic property of it. The adsorption ability of this magnetic mesoporous was studied for removal of methylene blue from aqua media.
