| 摘 要： | 采用空气氧化法制备了分散性较好的α-FeOOH纳米棒，并用XRD, SEM, N2吸附-脱附等手段对其进行了表征，在H2O2/α-FeOOH类Fenton条件下对甲基橙(MO)溶液进行处理，考察各种因素对溶液中MO降解的影响. 结果表明，在酸性介质中α-FeOOH能有效催化降解水溶液中的MO，降解率随H2O2初始浓度增加而增加，但当H2O2初始浓度达5.47 mol/L时，降解率反而下降. UV-Vis谱图显示，MO在80℃水浴中达到了很好的降解效果.

| Abstract: | The a-FeOOH nanorods with good dispersion were prepared by air oxidation synthetic method. The catalyst samples were characterized by N2 adsorption-desorption, XRD, and SEM. Methyl orange was treated with water-curing treatment in the presence of hydrogen peroxide and goethite. All kinds of influential factors were investigated. The results show that methyl orange can be more efficiently degraded in acid media. The catalysis degradation rate increases with the concentration of H2O2, but, with 5.47 mol/L initial concentration of H2O2, the efficiency is declined. UV-Vis spectra in the treatment show that the degradation of methyl orange in the water bath has attained good effects. |
