Influence of the magnetite synthesis pathway on the photo-Fenton degradation of sulfamethoxazole

Abstract Three magnetites were synthesized using different coprecipitation routes, designated S1, S2 and S3. The aim was to investigate the effect of catalyst surface properties on the efficiency of the photo-Fenton process and compared with a commercial magnetite. The synthesis started with Fe(II) and Fe(III) in the case of S1, with Fe(III) and potassium iodide as the reducing agent for S2, and with Fe(II), citrate and nitrate for S3.
