废水中的重金属污染对环境和公众健康构成严重威胁。磁性铁基材料在重金属废水处理、资源节约和金属离子回收利用方面具有重要的应用价值。以两种重金属废水为原料，制备了磁性可分离的MnFe 2 O 4和CuFe 2 O 4催化剂。采用扫描电子显微镜、X射线衍射仪、振动样品磁强计和X射线光电子能谱对催化剂进行了表征。结果表明，MnFe 2 O 4和CuFe 2 O 4 MNP能有效活化过一硫酸根（PMS），产生强大的硫酸根自由基，用于去除罗丹明B（RhB）。在0.4g/L MnFe 2 O 4 MNP和0.2g/L PMS的协同作用下，20 min内RhB（10 mg/L）降解率可达99%以上。PMS/WB-MnFe 2 O 4降解RhB的最佳pH值为3。在催化剂负载量为0.40 g/L、染料浓度为10 mg/L、PMS = 0.2 g/L、T = 25°C的条件下，染料的稳定性和重复使用性均较好。
AbstractHeavy metal contamination in wastewater poses a severe threat to the environment and public health. Magnetic iron-based materials are effective for heavy metal wastewater treatment, resources conservation, and recycling of metal ions. In the present work, two kinds of heavy metal wastewater were used to fabricate magnetically separable MnFe2O4 and CuFe2O4 as catalysts. The obtained catalysts were characterized by scanning electron microscopy, X-ray diffractometry, vibrating sample magnetometer, and X-ray photoelectron spectroscopy. Results showed that MnFe2O4 and CuFe2O4 MNPs could effectively activate peroxymonosulfate (PMS) to generate powerful sulfate radicals () for Rhodamine B (RhB) removal. More than 99% of RhB (10 mg/L) was degraded within 20 min using 0.4 g/L MnFe2O4 MNPs and 0.2 g/L PMS. The most effective pH for RhB degradation by PMS/WB-MnFe2O4 was 3. And under the condition of catalysts loading (0.40 g/L), dye concentration (10 mg/L), PMS = 0.2 g/L and T = 25°C, the stability and reusa...
