| titleOfInvention | A method for precipitating low-chloride lutetium oxide by chloride system |
| abstract | The invention discloses a method for precipitating low-chloride lutetium oxide in a chloride system, which comprises the following steps: (1) preparation of feed liquid: mixing and stirring LuCl solution with a concentration of 0.1-0.8 mol/L and concentrated nitric acid solution until forming Stable concentration of feed liquid, the concentration of nitrate in the feed liquid is 0.3~2.0mol/L; (2) Precipitating agent preparation: use oxalic acid solution with a concentration of 120~150g/L, heat until the solid oxalic acid in the oxalic acid solution is completely dissolved, (3) Precipitation and chlorine removal: use the co-current precipitation method to mix the bottom water, the above-mentioned feed liquid and the above-mentioned precipitant at a temperature of 35~60°C to react and precipitate, so that the reacted input lutetium chloride and The stoichiometric ratio of oxalic acid is n(lutetium chloride):n(oxalic acid)=1:(1.65~1.95); (4) Washing and removing chlorine radicals: washing the precipitated lutetium oxalate; (5) Burning: washing The final precipitate lutetium oxalate is burned to obtain low-chloride lutetium oxide products, which prevents the occurrence of chloride ion wrapping and powder agglomeration during the precipitation of lutetium oxalate, resulting in high impurities. |
