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.

利用Fenton铁污泥可持续降解废水中的磺胺嘧啶

以Fenton污泥（FS）和核桃壳（WS）为原料，经缺氧煅烧合成铁碳复合材料（FS@WSC-x/y），用于磺胺嘧啶的降解。通过改变FS/WS质量比(x)和煅烧温度(y)，确定了最佳条件（x = 1, y = 700℃），最大限度地提高了降解效率。进一步优化反应条件为40 μM磺胺嘧啶、10 mM H2O2、pH 2.0、0.050 g FS@WSC-1/700，在120 min内降解95%。
