| titleOfInvention | Hemicellulose-based hydrogel and preparation method and application thereof |
| abstract | The invention discloses a hemicellulose-based hydrogel and a preparation method and application thereof, belonging to the technical field of organic chemical industry. Carrying out graft modification on the viscose waste liquid by using allyl glycidyl ether, glycidyl acrylate or glycidyl methacrylate; then generating free radicals under the action of ammonium persulfate and N, N, N ', N' -tetramethyl ethylene diamine, and carrying out graft copolymerization with acrylic acid; adding a cross-linking agent N, N-methylene bisacrylamide, stirring for reaction to obtain a primary hydrogel product, and performing alkali treatment and drying to obtain the hemicellulose-based hydrogel. The invention directly uses the viscose waste liquid as the raw material to prepare the hemicellulose-based hydrogel, thereby not only effectively solving the treatment problem of the alkaline waste water generated in the viscose production process and improving the economic benefit of enterprise production, but also effectively solving the pollution problem of heavy metal ions in water because the hydrogel can be used for adsorbing the heavy metal ions. |
