A ABSORBENT COMPRISING HYDROPHOBIC MESOPOROUS MATERIAL FOR REMOVAL OF HARMFUL PHARMACEUTICALS FROM AQUEOUS ENVIRONMENT

摘要

PURPOSE: An absorbent containing hydrophobic mesoporous material for removing harmful pharmaceuticals from aqueous environment is provided to improve the removal efficiency of a harmful pharmaceutical eliminating process. CONSTITUTION: An absorbent for organic pharmaceuticals includes trimethyl silylated SBA-15. The specific surface area, the pore volume, and the pore size of the trimethyl silylated SBA-15 are respectively in a range between 400 and 600m^2/g, in a range between 0.7 and 0.9 cm^3/g, and in a range between 6 and 8nm. A method for manufacturing the trimethyl silylated SBA-15 includes the following: the mixed solution of pluronic P123 and tetraethyl ortho silicate is prepared in an acidic solution; the mixed solution is kept at a temperature between 25 and 40 degrees Celsius for 10 to 30 hours and further stirred at a temperature between 80 and 120 degrees Celsius for 20 to 30 hours; the stirred mixed solution is washed with deionized water; the washed solution is calcinated at a temperature between 400 and 600 degrees Celsius for 43 to 8 hours to obtain SBA-15; the SBA-15 is pre-treated at a temperature between 170-210 in a vacuum state for 10 to 14 hours; toluene anhydride is added into the pre-treated SBA-15 to obtain slurry liquid; the slurry liquid is stirred with hexamethyl disilazane is stirred at a temperature between 25 and 30 degrees Celsius under a nitrogen atmosphere for 20 to 30 hours to obtain the trimethyl silylated SBA-15, and the trimethyl silylated SBA-15 is filtered.
