制备了一种新型铁与活性炭毡复合材料,应用于芬顿反应降解水中污染物亚甲基蓝染料。结果表明,该复合材料对亚甲基蓝染料具有良好的去除效果。另外,该研究对溶液中pH和H2O2浓度进行了优化,并对该复合材料的重复利用效果进行了尝试,结果重复使用9次,降解效率未发生明显降低,同时溶液中释放的铁离子浓度也保持在较低水平(0.3mg/L),因此Fe/ACF复合材料在芬顿反应降解水中污染物方面具有一定的开发利用价值。
A new complex material from iron and ACF(Fe/ACF)possessed heterogeneous Fenton catalytic activity were prepared,and methylene blue(MB)was chosed as a typical contaminant to evaluate the ability of Fe/ACF on degradation of organic pollutants dissolved in water.The results showed that the Fe/ACF was high efficiency in degradation of MB,and the operation conditions of MB degradation,such as pH and H2O2 concentration of reaction system,were optimized.Repetitive photodegradation experiments were carried out,the results showed that even recycling up to 9 times,there was no significant decline in degradation efficiency,this demonstrated that the Fe/ACF could be reused in MB removal;additionally,the concentration of iron kept on low level(0.3 mg/L).Consequently,the Fe/ACF prepared in this article was high potential application in degradation of organic pollution in water.
