One-Step Synthesis of Metal-Modified Nanomagnetic Materials and Their Application in the Removal of Chlortetracycline.

ABSTRACT: Magnetic nanomaterials are promising heterogeneous catalysts for environmental applications. According to X-ray diffraction, Brunauer-Emmett-Teller method, scanning electron microscopy, high-resolution transmission electron microscopy, and vibrating-sample magnetometer, a kind of copper-modified nanomagnetic material (Cu-nFe3O4) was successfully prepared by a one-step synthesis method. Among them, compared with the two-step synthesis method of Cu/Fe3O4 and Cu/nFe3O4, Cu-nFe3O4 has the best effect on chlortetracycline (CTC) removal. The batch study results indicate that the maximum removal of chlortetracycline is 99.0% at a dosage = 2.0 g L-1, copper loading = 0.8 mM, and C 0 = 100 mg L-1 at the optimum conditions within 90 min. The effects of humic acids (HA), NO3 -, Cl-, CO3 2-, and PO4 3
