| titleOfInvention | From mixing the lutecium oxide and recovery method that reclaim Cerium aluminate lutetium scintillation crystal waste |
| abstract | The invention discloses a kind of from mixing the lutecium oxide and recovery method that reclaim the scintillation crystal waste of Cerium aluminate lutetium.The method comprises the following steps: S1, in scintillation crystal waste, add sodium hydroxide and/or potassium hydroxide, roasting, obtains calcining matter; S2, calcining matter is carried out water logging, filter, and add nitric acid and oxygenant in the filter residue obtained, stir, obtain mixed solution; S3, mixed solution is joined in organic extractant, extraction, obtain the extract containing cerium and the raffinate containing lutetium; And S4, to containing lutetium raffinate in add oxalic acid, stir, filter, by the throw out calcination obtained, obtain lutecium oxide.Adopt technique of the present invention to obtain high purity 99% and the rate of recovery up to 99.5% lutecium oxide, present invention process flow process is short, facility investment is few, simple easy handling, save resource, decrease pollution, there is huge practical value, provide and a kind ofly from the scintillation crystal waste of mixing Cerium aluminate lutetium, reclaim the new approach of lutetium. |
