| titleOfInvention | Preparation method of waste paper-based recyclable aerogel for oil-water separation |
| abstract | A preparation method of waste paper based recoverable aerogel for oil-water separation comprises pulverizing waste paper, dispersing in dilute hydrochloric acid solution, filtering, collecting precipitate, washing with deionized water to neutrality, and drying the precipitate; dispersing the precipitate in deionized water, stirring to form uniform pulp, adding Fe 3 O 4 Uniformly stirring the nano particles and epoxy chloropropane, freeze-drying, and placing in an oven for treatment to obtain the waste paper-based magnetic aerogel; and soaking the prepared aerogel in a dopamine ethanol solution, taking out the aerogel and drying at room temperature, then soaking the aerogel in a hydrophobic agent, and drying at room temperature to obtain the waste paper based recyclable aerogel for oil-water separation. The absorbable oil-gas gel material is prepared by taking the domestic waste paper fiber as the raw material, so that the invention is not only beneficial to relieving the crisis of petrochemical resource shortage, but also provides a new way for the high-value utilization of wastes. |
