Abstract

Iron-carbon composites (FS@WSC-x/y) were synthesized from Fenton sludge (FS) and walnut shells (WS) via hypoxic calcination for sulfadiazine degradation. By varying FS/WS mass ratios (x) and calcination temperatures (y), optimal conditions (x = 1, y = 700 °C) were identified, maximizing degradation efficiency. Reaction conditions were further optimized to 40 μM sulfadiazine, 10 mM H₂O₂, pH 2.0, and 0.050 g FS@WSC-1/700, achieving 95 % degradation within 120 min.
