The invention discloses attapulgite-
polyacrylic acid nanocomposite gel with the high adsorptivity and a preparation method thereof. The attapulgite-
polyacrylic acid nanocomposite gel is characterized by being prepared from, by weight, 2-4 parts of nano-
zeolite powder, 5-10 parts of attapulgite, 1-2 parts of
silicon dioxide, 15-20 parts of a
hydrochloric acid solution, 30-40 parts of a
zinc sulfate solution, an appropriate amount of absolute ethyl
alcohol, 1-3 parts of nylon fibers, 2-5 parts of a
silane coupling agent KH-570, 2-5 parts of a
silane coupling agent KH-550, 2-3 parts of
chitosan, 0.4-1 part of cerous
nitrate, 5-10 parts of
acrylic acid, an appropriate amount of
nitrogen and an appropriate amount of
distilled water. According to the attapulgite-
polyacrylic acid nanocomposite gel with the high adsorptivity and the preparation method thereof,
chitosan added in a cooperative mode is rich in amino groups, and therefore not only can the amino groups be provided to be grafted on attapulgite to participate in crosslinking to enhance the stability of the
network structure of the gel, but also the carrier adsorption amount of carriers can be increased due to the fact that
chitosan has the very good adsorptivity; by adding the nano-
zeolite powder and the like in a cooperative mode, the advantages of being good in adsorption performance and high in strength are given to the material.
