The invention discloses a preparation method, product and application of aerogel for radioactive wastewater treatment. Solvent replacement is carried out in an organic solvent, then a cross-linking agent is added for chemical cross-linking, and aerogel is obtained by drying. The surface of the aerogel has a large number of carboxyl and phenolic hydroxyl active functional groups that can be complexed with a variety of radionuclide metal cations. It has large specific surface area, high mechanical strength, and has a large number of carboxyl and phenolic hydroxyl active groups, which has good adsorption performance for radionuclides in wastewater, and is suitable for adsorption treatment of radioactive wastewater. |
