摘 要: | 以浸渍法制备了系列Fe~(2+)/活性炭材料,X射线衍射、X射线光电子能谱和扫描电子电镜分析结果表明,形貌未变的活性炭载体负载了铁离子。将所制材料应用于类Fenton体系降解废水中苯酚的实验研究,结果表明,在焙烧温度为500℃,铁离子负载量为0.49 mmol/g条件下制备的Fe~(2+)/活性炭材料的催化活性最高,其与双氧水组成的类Fenton体系在60 min内对苯酚的降解率为83%。该材料在循环使用时稳定性好,经5次使用后其活性仅下降8%。

AppIication of Fe2+/activated carbon to Fenton-Iike system for the degradation of phenoI in wastewater |

Abstract: | Series of Fe2+/activated carbon materials have been prepared by immersion method. The analytical results through X-ray diffraction,X-ray photoelectron spectroscopy and scanning electron microscope indicate that the ac-tivated carbon whose appearance was not changed has been loaded with Fe ions. The prepared Fe2+/activated carbon is applied to the experimental research on Fenton-like system for the degradation of phenol in wastewater. The expe-rimental results show that the catalytic activity of the prepared Fe2+/activated carbon materials is the best,when cal-cining temperature is 500℃,and the carrying capacity of iron ions 0.49 mmol/g. The degradation rate of phenol is 83%,when the Fenton-like system is combined with hydrogen peroxide for no more than 60 min. The materials have excellent stability while being used circularly. After being used for 5 times ,the loss of activity is only 8%. |
