| 摘 要： | 以聚乙二醇（PEG-10000）辅助，在室温（25℃）-F由MgCl2-6H2O与Na2CO3通过层一层自组装制备出具有六棱柱状形貌的MgO，并以其对含铅溶液的吸附为探针反应，研究其对重金属离子的吸附性能．研究结果表明，所制备氧化镁的前驱体为MgCO3·3H2O；经600℃焙烧得到的六棱柱状MgO比表面积大于55m^2／g，具有良好的吸附性能；对含铅溶液的吸附过程符合Langmuir等温吸附，饱和吸附量达到390mg／g．

| Abstract: | A novel hexagonal columnar MgO was synthesized by precipitation method assisted by structure director （PEG-10000）. Experiment results show that this hexagonal columnar structure can be explained by self-assemble with layer by layer. The precursor of MgO was nesquehonite, and MgO with large surface area （〉 55 m2/g） was obtained after calcination at 600 ~C. The adsorption performance of hexagonal columnar MgO was also studied in lead solution, and saturated adsorption was 390 mg/g. The results of adsorption are conformed to Langmuir model, which mean that the novel hexagonal columnar MgO has a high adsorption performance. |
