摘　　要：通过溶胶-凝胶法制备了有序多孔的TiO_2材料。通过共混、反相悬浮、交联制备了壳聚糖/二氧化钛(CHS/TiO_2)复合材料,研究了制备材料的吸附性能。结果显示,复合材料的吸附性能优于TiO_2和壳聚糖的吸附性能。比表面积(BET)分析表明,复合材料的比表面积稍大于TiO_2的比表面积,且所制备的材料为介孔分布材料。In this paper,ordered porous TiO2 materials were prepared by use of the sol-gel method and TiO2/CHS compound materials were prepared by application of the blending,opposition aerosol and cross-linking methods.Adsorption performance of the materials was also studied.The results showed that adsorption performance of the compound materials was better than that of TiO2 and CHS,The results of BET analysis indicated that surface area of the compound materials was slightly bigger than that of TiO2,and the prepared compound materials were porous.
