▎ 摘　　要

NOVELTY - Amino-silanization of the graphite alkenyl oxide adsorbing material, is claimed. The preparation method is as follows: introducing a silane reagent into the graphene oxide alkenyl group, further into the polyvinyl alcohol polymer chain and combining the gradient temperature vacuum drying technology to obtain strength-enhanced aminosilylated graphene oxide alkenyl macroscopic material. The obtained aminosilized graphene oxide alkenyl macroscopic material is a material having a network pore structure having a specific surface area of 800-2600 m2 /g and a pore volume is 0.33-2.2 m3/g. The pore structure comprises less than or equal to 5 nm diameter micro-aperture of 5-20 nm holes, the aperture is 20-60 nm of the middle hole, and the aperture is greater than or equal to 50 nm of the large hole. USE - The material is use for removing the heavy metal pollutant in water (claimed). ADVANTAGE - The method is simple, low mild reaction condition, low energy consumption, controllable product and economical. The material avoids the secondary pollution problem of adsorbent, does not improves the heavy metal pollutant in the water absorption performance of the material, improves the mechanical strength of the material and improves the circulation performance and has high practical value.
