| Abstract: | A method for preparation of mesoporous composite materials was investigated which is the combi-nation of destructive pore-making technique and organic composite method. The final product made by the methodpossesses excellent absorbent property for both small inorganic molecules and big organic molecules in pollutedwater, and it is also a kind of bactericide. By the acid etching technique, many impurities in matrix materials wereremoved and pore canals were etched. The moisture absorption rate of the semifinshed product for 24h is 2 timesas large as that of the raw material, and the adsorption amount for dye is 1.6 times. |
