岩矿中稀土元素离子交换分离富集的改进及ICP-AES测定
IMPROVEMENTS OF ION -EXCHANGE SEPERATION AND BENEFICATION METHODS IN THE DETERMINING REE OF ROCK MINERALS WITH ICP-AES
【摘要】 本文通过对离子交换柱的规格改进,提高了分离效率,加快了分离速度(流速v/(ml·min-1))可达1.0—1.5.结合分离富集条件的选择及ICP-AES测定方法的联用,使本法不分析周期短、所耗试剂省,且检测限低、精密度和准确度较高.经标样检验和矿样实测对比,其结果均令人满意.
【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.
