【Abstract】 With the improvements of ion-exchange column ,the seperating efficiency of rare-earth elements has been raised and the seperating velocity been speeded up to 1.0 ml/min to 1. 5 ml/ min. The new technological process has the advantages of shorter analysis period,less reagent volume, lower detecting limits,higher precision and accuracy than the old one by selecting the seperating and beneficiating conditions suitable to the determining methods of ICP - AES. This method and its process have been tested by determining standard samples and ore samples simultaneously.更多还原
