Abstract
Series magnetic MgFe2O4/MIL-88A catalysts (MFxMy) were fabricated by a simple ball-milling method, which were applied to degrade sulfamethoxazole (SMX) antibiotic via photo-Fenton process under low power visible light. The influences of initial pH, H2O2 concentration, and co-existing inorganic anions on SMX degradation were explored. The results revealed that the optimal MgFe2O4/MIL-88A (MF140M60) demonstrated excellent photo-Fenton catalysis activity, in which ca. 99.8% of SMX could be degraded within 20.0 min. The outstanding catalytic activity of MgFe2O4/MIL-88A (MF140M60) can be ascribed to the effective transfer of charge carriers between MgFe2O4 and MIL-88A. As well, the optimal MgFe2O4/MIL-88A (MF140M60) catalyst possessed good stability and recyclability.
