摘　　要：探索了一种制备介孔复合环境材料的方法——破坏式造孔与有机复合相结合,使最终产品可大量吸附污染水体中的各种污染物并具有一定的杀菌功能.该方法通过酸洗刻蚀,达到了去除原材料中的杂质和刻蚀孔径的目的,所制备的中间产品24 h吸湿率为原材料的2倍,染料吸附量为原材料的1.6倍.A method for preparation of mesoporous composite materials was investigated which is the combination of destructive pore-making technique and organic composite method. The final product made by the method possesses excellent absorbent property for both small inorganic molecules and big organic molecules in polluted water, and it is also a kind of bactericide. By the acid etching technique, many impurities in matrix materials were removed and pore canals were etched. The moisture absorption rate of the semifinished product for 24 h is 2 times as large as that of the raw material, and the adsorption amount for dye is 1.6 times.
