摘要
稀土试样经草酸沉淀、过滤以除去大部分杂质和非稀土元素,灼烧灰化后用稀盐酸溶解。试液经P_(507)萃取色层柱,使钇与轻稀土元素分离,再经N_(263)萃取色层柱,使钇与重稀土元素分离。用EDTA标准溶液滴定,可测得氧化钇的含量。
The sample rare earth has been precipitated and leached by the oxalid acid,we can eliminate the most part of the impurity and the nonrare earth element and dissolve it with the dilute hydrochloric acid after burning out. The sample solution has been separated with light rare earth element through the P507 chromatograph column,then sepertated with the heavy rare earth element through the N263 chromatograph column. We can measure the contents of yttrium with EDTA standard solution titration.
