  本研究采用传统的高级氧化技术之一的芬顿氧化(Fenton)降解孔雀石绿模拟印染废水,研究了铁粉为铁源的非均相芬顿反应的降解效果,检测并对比降解前后的色度、CODCr等的去除率,得出最适宜反应条件.铁粉法实验结果表明,在pH为2.6,H2O2浓度1.5mmol/L时(铁粉过量),色度、CODCr、孔雀石绿的去除率达99.6%、96.6%和99.1%,铁粉法非均相芬顿和传统硫酸亚铁试剂法的去除率相近,表明此时铁粉氧化所耗氧化剂所占比例不大,且未对去除率产生显著影响.

石墨烯基材料具有独特的物理化学生质因而是一种良好的吸附材料,但吸附过程中易团聚、吸附完成后难以分离再生等问题限制了其应用范围。磁性石墨烯基复合材料不仅结合了石墨烯基材料的优良吸附能力和磁性材料易于分离的特性,还解决了是石墨烯基材料易团聚和重新堆积的问题,在水处理领域有广阔的应用前景。文章介绍了石墨烯及磁性石墨烯基复合材料的常用合成方法,并着重阐述了其在去除废水中金属离子和难降解有机污染物等水处理领
