▎ 摘  要

NOVELTY - Preparation of Mxene membrane adsorption material based on polyamidoxime comprises treating raw materials with hydrogen fluoride for 0.1-2 hours at 0-18 degrees C with pH of 4-10; at 10-60 degrees C and pH of 5-10, soaking raw materials in dimethylsulfoxide solution and sonicating for 0.1-1 hour to form Mxene membrane; and soaking Mxene film in polyamidoxime solution for 1-12 hours at 20-40 degrees C, pH of 5-7 and pressure of 0.1-0.17 MPa, vacuum filtering polyamidoxime solution, washing with pure water, and drying for 6 hours. USE - The method is used for preparing Mxene membrane adsorption material based on polyamidoxime for uranium extraction in seawater, radioactive seawater treatment, precious metal recovery, environmental remediation, industrial wastewater treatment and/or seawater desalination (all claimed). ADVANTAGE - The method is simple. The raw material is rich. The reaction condition is mild. The energy consumption is low. The prepared material has good adsorption performance.
