| titleOfInvention | A method for radioactive wastewater treatment and radionuclide recovery |
| abstract | A method for radioactive waste water treatment and radionuclide recovery, which is characterized by comprising the following steps: step 1, adjusting the pH of the radioactive waste water until the pH is 6 to 12; the pH adjustment process requires stirring to make the pH of the radioactive waste water everywhere uniform; step 2, adding nano-magnetic particles to the wastewater, stirring and mixing for a reaction time of 2 to 60 minutes, and dissociation treatment temperature of 5 to 90 ° C, so that the nano-magnetic particles and radionuclides are combined to form magnetic particle-radionuclide complexes ; wherein, the nano-magnetic particles are of core-shell structure, the inner core is one of ferrite, ferric oxide, or ferric oxide particles, and the outer shell is silicon oxide, zirconium oxide, aluminum oxide, chitosan or one of the porous carbons, the nano-magnetic particles have a particle size of 3-1000 nm; the invention provides a method for treating wastewater containing radionuclides and recovering radionuclide resources, which has the advantages of simple treatment process, and the types of chemicals used are The dosage is small and does not require the characteristics of organic binders. |
