Abstract

Abstract:

Iron oxides nanomaterials has been synthesized using glycine as structure-directing agent via a simple hydrothermal method.The samples are characterized that the resulting products are hexagonal phase of α-Fe₂O₃.The morphology of α-Fe₂O₃can be turned from irregular nanoparticles to cross-linking porous structure by simply regulating the concentrations of glycine.The specific surface area of the sample is 72.7 m ² /g.The effects of adsorption time and initial p-nitrophenol concentration on adsorption capacity are investigated,via static adsorption experiment of p-nitrophenol in water with the sample.It is found that adsorption kinetics follows the pseudo-second-order kinetic equation model.The adsorption equilibrium data are best fitted by Langmuir isothermal model,with maximum adsorption capacity of 101.5 m ² /g.

Key words: nanometer iron oxide, hydrothermal synthesis, p-nitrophenol, adsorption capacity

摘要：

以甘氨酸为结构调节剂,水热法合成了纳米氧化铁材料。对样品进行了表征,结果显示:样品为六方晶系α-Fe₂O₃。调节甘氨酸浓度,可使样品从不规则纳米颗粒逐步转变为交联多孔网状α-Fe₂O₃,其比表面积达到72.7m²/g。通过样品对水中对硝基苯酚的静态吸附实验,考察了吸附反应时间和初始浓度对吸附性能的影响,发现其吸附动力学符合准二级动力学方程,吸附平衡符合Langmuir等温吸附模型,其饱和吸附量为101.5 m²/g。
