| titleOfInvention | A kind of nanometer Fe3O4 grafted polyacrylic acid-based hydrogel adsorption material and preparation method thereof |
| abstract | The invention relates to the technical field of magnetic adsorption materials, and discloses a nano-Fe 3 O 4 grafted polyacrylic acid-based hydrogel adsorption material, comprising the following raw materials and components, functionalized nano-Fe 3 O 4 , acrylic acid, acrylamide, Azobisisobutyronitrile, N,N'-methylenebisacrylamide. RAFT reagent 4-cyano-4-[[(dodecylthio)thione methyl]sulfanyl]valeric acid is esterified with the hydroxyl group on the surface of nano Fe 3 O 4 to obtain functionalized nano Fe 3 O 4 , using azobisisobutyronitrile as an initiator, and functionalized nano-Fe 3 O 4 as a macromolecular chain transfer agent, through the RAFT reversible addition-fragmentation chain transfer polymerization method, acrylic acid and acrylamide were synthesized on the surface of nano-Fe 3 O 4 In situ polymerization, the nano-Fe 3 O 4 is tightly combined with the polyacrylic acid-based hydrogel, which is difficult to fall off and phase separation, and the gel adsorption material has excellent complexation to heavy metal ions such as Cd 2+ , as well as organic dye pollutants The effect of adsorption, magnetic adsorption and magnetic recovery. |
