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 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 semifinshed product for 24h is 2 times as large as that of the raw material, and the adsorption amount for dye is 1.6 times.
Keywords:zeolite  destructive pore-making technique  acid etching technique  mesoporous composite environmental material  organic substance
