首发时间:2014-04-16
摘要:利用聚苯乙烯(PS)微球模板法制备具有大孔-介孔分级孔结构和高比表面积的改性赤泥(MRM-PS),运用X射线衍射仪(XRD)、氮气吸附仪(N2-sorpotion)、扫描电镜(SEM)、透射电镜(TEM)等现代分析测试手段对样品进行了表征,并研究了其对有机染料污染物罗丹明B的吸附性能。结果表明,改性赤泥吸附剂MRM-PS对大分子有机染料污染物具有较理想的吸附效果。

Study on the modification and adsorption performance of modified red mud to Rhodamine B
Abstract:Modified red mud (MRM-PS) was prepared via a template synthesis method by using polystyrene (PS) microspheres and waste red mud. The textural and structural properties of the as-prepared sample was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and N2 sorption techniques. The analysis results revealed a hierarchical macroporous-mesoporous nanoparticle system with high surface area and uniform pore-size distribution. The results of adsorption performance measurements showed that the Rhodamine B adsorption on the prepared MRM-PS adsorbent was a fast process.
Keywords: Red mud Modification template synthesis method adsorption Rhodamine B
