| 摘 要： | 萃取树脂作为一种化学分离手段,国外七十年代就有报导,近年国内兄弟单位研制合成了各类型萃取树脂,并相继用于分析工作中,P_(507)萃取树脂最近问世,给稀土元素的分离富集带来了佳音。该树脂是在P_(507)萃取色层的基础上研制而成的,并具有离子交换的优点。本文研究了P_(507)萃取树脂分离稀土的条件及偶氮氯膦—PN与稀土元素的显色反应;拟定了一个

Spectrophotometric Determination of Micro amounts of Rare Earths in Minerals with CPA--PN after the Separation with P5o7Exteraction Resin |
| |
| Abstract: | An extraction chromatographic method for determination of rare earths in
minerals with P507 resin at pH 2-3 hydrochloric acid medium was stu4red. By
using a mixture solutiop of ammonium chloride, ascorbic acid and sulfosalicylic
acid as eluates, REE was determined with chlorophosphonazo-PN. |
