More Information
Summary:The invention discloses an extracting and purifying method of dysprosium oxide. Existing roughly machined collected low-purity dysprosium oxide is re-purified through the steps of to-be-purified solution preparation, intermediate agent preparation, separation column preparation, elution column transformation, adsorption operation, eluent ion exchange operation, sampling analysis according to a collected solution in volume, sediment concentration, merging and collection, liquid waste treatment and the like, so that the purity of the dysprosium oxide is up to 99.998 to 99.99999 percent. 本发明公开了种氧化镝的提取纯化方法，通过配置待提纯液、中间剂配置、分离柱准备、淋洗柱转型、吸附操作、淋洗离子交换操作、按体积收集液进行取样分析，集中沉淀合并收集、废液处理等步骤，将现有粗加工收集的低纯度氧化镝进行再提纯，使得氧化镝纯度达到99.998~99.99999%。
