用对叔丁基亚磺酰基杯[4]芳烃浸渍Amberlite XAD-7树脂。在pH 5.4左右，铌（V）以大于90%的产率收集在浸渍树脂上，而钽（V）的收集可忽略不计。收集的铌（V）用9 M硫酸几乎定量地解吸，因此成功地实现了铌（V）与钽（V）的分离。(c)2005 Elsevier B. V.保留所有权利。
Amberlite XAD-7 resin was impregnated with p-tert-butylsulfinylcalix[4]arene. Niobium(V) was collected on the impregnated resin in yields of more than 90% around pH 5.4, whereas tantalum(V) was negligibly collected. The collected niobium(V) was desorbed with 9 M sulfuric acid nearly quantitatively, hence the separation of niobium(V) from tantalum(V) was successfully achieved. (c) 2005 Elsevier B.V.
