The invention discloses a preparation method of a super-hydrophobic
active carbon modified material. The material is prepared by applying a chemical
liquid phase impregnation method, using trimethylchlorosilane as a modifier, using absolute
methanol as a
solvent, respectively using pre-processed
coal columnar
active carbon and coconut shell granulated
active carbon as carriers, impregnating via
liquid phase,
drying in vacuum, and commonly blowing air and
drying. The hydrophobic performance is respectively detected through a
contact angle test and a
liquid water adsorption experiment; and the adsorption is checked by using
benzene adsorption experiment and an
iodine value test. The invention has the advantages of simple preparation process, less
material consumption and wild preparation condition; and the preparation method is carried out at
room temperature. The prepared active carbon modified material has super-hydrophobic
surface chemical performance and great pore volume, which makes up the shortcomings of easy absorption of
moisture in the multi-pore carbon material with
high humidity and small
absorption capacity of the target organic matters; and the prepared active carbon modified material is easy to recycle and can be repeatedly recycled, so that the industrial cost is reduced and a foundation is further laid for the industrialized application.
