P507萃淋树脂已广泛用于萃取色谱法分离制备高纯钆、铽和镝,也广泛用于稀土元素的分析。我们以前的工作说明了 P507萃淋树脂是浸渍型树脂,P507与苯乙烯-二乙烯苯共聚物载体之间没有化学键合。本文利用红外光
P507 extraction resin has been widely used for the separation and preparation of high purity gadolinium, terbium and dysprosium by extraction chromatography. It is also widely used for the analysis of rare earth elements. Our previous work shows that the P507 extraction resin is an impregnating resin and that there is no chemical bonding between the P507 and the styrene-divinylbenzene copolymer support.
