Description
The behaviour of solvent extraction of niobium is discussed. The expractants, includding TBP, HDBP, H2MBP, TBP irradiated, HDEHP, TTA and Aliquat-7402, are used. The special influence of molybdenum and zirconium on solvent extraction of niobium and the extraction behaviur of niobium with TBP irradiated are described. The effect of fluorine and uranium in aqueous phase on extraction of niobium is mentioned. It is observed that the interfacial crud has not relevance to DNb, but niobium-95 can be absorbed on it. The species of extractable niobium, extraction mechanism, and the reason brought niobum into organic phase are discussed. Finally, the idea of increasing decontamination factor for niobium is suggested
