Abstract

GO/CoFe2O4 was synthesized by coprecipitation to remove the environmental pollutants efficiently in the water. Dibutyl phthalate (DBP) was removed using the GO/CoFe2O4-catalyzed peroxymonosulfate (PMS). GO/CoFe2O4 was characterized by SEM

TEM

XPS and XRD. DBP removal efficiency was studied under different conditions in the water. The results showed that

at room temperature

the removal rate of DBP in the anometer spinel granulated GO/CoFe2O4/PMS oxidation reaction system

with the initial DBP concentration of 2 μmol/L

catalysts dosage of 0.1 g/L

PMS concentration of 20 μmol/L and pH of 7.0. The removal efficiency of DBP only decreased 5% after 5 times. The new composite catalyst had a potential engineering application prospect due to its high efficiency and easy recovery.
