摘      要：Hydroxyquinoline 5 sulfonic acid, covalently bound to filter cellulose, was used for preconcentrating trace rare earth element(REE) ions from complex matrices and matrix separation, respectively. Multi REE ions were preconcentrated on the column filled with 8 hydroxyquinoline 5 sulfonic acid cellulose filter and analysed by ICP AES after being eluted with dilute HNO 3. In the given pH range, alkali and alkaline earth metal ions can be separated as matrix elements; a high concentration factor is obtained and the eluates can be measured without interference. The usefulness of the method is shown by the control analyses of standard reference materials. [WT5FZ]
